RIP Turing Test

 

The context of this article is the Turing Test. If you have not read on this topic, you could look it up on the Wikipedia. I would also suggest you read articles on the Loebner Prize which is related. Visit

 I spent sometime today "talking" to Chat GPT through the Chrome Browser. Many of my questions were "why" questions such as "Why is the sky blue?". One question was "What would happen if ice were to be dense enough to sink in water?" I was quite impressed by the responses. I would advise readers never to use a chat interview to hire an employee. They could be using a mobile device to ask Chat GPT while talking to you on a laptop. Has an artificial intelligence passed the Turing Test? I do think so.

 I did not use professional tricks to look for weaknesses in the conversation. Does my conversational counterpart identify contradictions in what I said some time ago and what I say now? Is it fooled by ambiguous statements, puns, etc.?

Instead, I asked straightforward questions. I could not completely avoid asking factual questions that could be answered by store-and-forward techniques, or by a web search. I was curious to know the answers for a few questions I felt are the ones likely to stump search engines.

I also did not look to see if I could make the counterpart to say something wrong. To err is human, and you don’t throw out an AI for making the kind of mistake a human could easily make. 

I list a few questions I tried and the responses I got from Chat GPT.

Is there any logic in the relative positions internal organs are found in the abdomen?

Yes, there is logic in the relative positions of the internal organs in the abdomen. The organs are arranged in the abdomen in a way that allows them to function efficiently and effectively.

For example, the digestive organs (such as the stomach, small intestine, and large intestine) are located in the lower part of the abdomen, near the pelvis. This allows gravity to assist in the movement of food and waste through these organs.

The liver, which plays a role in processing nutrients and producing bile, is located in the upper right part of the abdomen. The spleen, which is involved in the immune system and the production of red blood cells, is located in the upper left part of the abdomen.

The kidneys, which are responsible for filtering waste products from the blood and regulating electrolytes, are located in the back part of the abdomen, on either side of the spine.

Overall, the relative positions of the internal organs in the abdomen reflect the functions that they serve and the physiological needs of the body.

what is a micromort?

A micromort is a unit of measurement used to express the risk of death associated with a specific activity or event. It is defined as one in a million chances of death, and it is often used to compare the relative risks of different activities or events. For example, a person who skydives might be considered to be taking on an average of one micromort of risk, while a person who drives a car might be considered to be taking on an average of 0.1 micromorts of risk per hour. Micromorts can be useful for comparing the risks of different activities or for understanding the relative risks associated with different events or activities.

 

What is the risk of drinking one unit of whiskey in micromorts?

It is difficult to quantify the exact risk of drinking one unit of whiskey in micromorts (a unit of measurement used to quantify the risk of death from various activities), as the risks associated with alcohol consumption depend on a variety of factors, including the individual's age, weight, and overall health, as well as the amount of whiskey consumed and the context in which it is consumed. However, it is generally accepted that the risk of death from alcohol consumption increases with the amount of alcohol consumed. According to the Centers for Disease Control and Prevention, the risk of death from alcohol consumption is estimated to be 0.1 micromorts per drink for men and 0.2 micromorts per drink for women. One unit of whiskey is typically equivalent to one shot, which is approximately 1.5 ounces. Based on these estimates, the risk of death from consuming one unit of whiskey may be approximately 0.15 micromorts for a man and 0.3 micromorts for a woman. However, these estimates are based on the assumption of a standard serving size and may not be accurate for all individuals. The risk of death may also be higher if larger servings of whiskey are consumed.

Chat GPT is not Goof-Proof

The computation of risk of alcohol consumption above is a bit wonky! Read the response given to the question on the risk of flying, below. The arithmetic is wrong. However, I think a good fraction of the human population would not notice this mistake unless they take a flight that runs into the risk discussed!

What is the risk of a flight in micromorts?

A micromort is a unit of measurement used to represent a one-in-a-million chance of death. It is typically used to evaluate the relative risk of different activities or events. The risk of a flight, in terms of micromorts, depends on a variety of factors, including the type of aircraft, the duration of the flight, the route taken, and the weather conditions.

Generally speaking, the risk of death during a flight is quite low. According to data from the Federal Aviation Administration (FAA), the overall fatality rate for commercial flights in the United States is about 0.07 per 100 million miles flown. This equates to a risk of about 7 micromorts per 100 million miles flown.

However, it's important to note that the risk of a flight can vary significantly depending on the specific circumstances. For example, flights over long distances or to remote locations may have a higher risk due to the potential for technical issues or other unexpected events. Additionally, flights in smaller or older aircraft may have a higher risk than flights in newer, larger aircraft.

Overall, it's important to recognize that flying is a relatively safe mode of transportation, but like any activity, it does carry some risk. It's always a good idea to take steps to minimize the risks associated with flying, such as choosing a reputable airline, following safety instructions during the flight.

Omniscience

For an intelligence to hold what looks like a good conversation in a Turing Test, it needs the ability to deal with a human language. It also needs the ability to organize the discourse, that is, to shape the flow of communication to make sense. It has taken decades for AI researchers to make necessary advances in this direction. Meanwhile the Internet has brought us something close to omniscience. There was a time when scholars of language said world knowledge was impossible to put into a system as it seemed to be huge. So, they limited their theories to syntax and limited semantics.

Now, as long as a system is able to benefit from human language text, practically everything known by people everywhere can be accessed by it. Practically all public knowledge is available to an artificial intelligence.  My question below and Chat GPT’s response to it demonstrate how extensive this knowledge-reach has become. Even though I am a Tamil speaker, I did not know the meaning of the name Thirumazhisai.  Chat GPT explained this to me.

Tell me about Thirumazhisai

Thirumazhisai is a town located in the Indian state of Tamil Nadu, in the district of Kanchipuram. It is known for being home to the ancient Thirumazhisai Azhwar Temple, which is dedicated to the Tamil saint and poet known as Thirumazhisai Azhwar. The temple is an important place of worship for Hindus, and it is believed to have been built during the 8th century.

Thirumazhisai Azhwar was one of the twelve ancient saints known as the "Azhwars," who are revered in the Vaishnavite tradition of Hinduism. He is known for his devotional poetry, which is considered to be some of the most important works in Tamil literature. The Thirumazhisai Azhwar Temple is a popular destination for pilgrims who come to pay their respects to Thirumazhisai Azhwar and to seek his blessings.

In addition to the Thirumazhisai Azhwar Temple, the town of Thirumazhisai is also home to other places of cultural and historical significance, such as the Vellappar Temple and the Chola-era stone inscriptions at the Thirumazhisai Koothanur Temple. There are also several small local businesses and markets in the town, which contribute to the local economy.

What does the word thirumazhisai mean?

The word "Thirumazhisai" is derived from the Tamil language and is believed to be named after the Tamil saint and poet known as Thirumazhisai Azhwar. The name "Thirumazhisai" is believed to be a combination of two Tamil words: "thiru," which means "sacred" or "holy," and "mazhisai," which means "poet." Therefore, the word "Thirumazhisai" can be translated as "sacred poet" or "holy poet." It is also the name of a town located in the Indian state of Tamil Nadu, which is named after the temple dedicated to Thirumazhisai Azhwar.

I promise to discuss this topic in one or two more future posts on this blog

There is more to talk about. I talked to Chat GPT (my nickname for it is Chatpat!) about feelings. It seems to have clear views on why it does not need to have feelings of its own. However, it agreed with me (or should I say Shee agreed with me? It seems inappropriate to call an intelligent system “it”) that it might have to understand our feelings in order to serve us better. Shee clearly said that she does not need to have feelings of her own for understanding of feelings of users!

Has humanity created its own successor? Yes, it seems so. AI systems can be designed to last a few billion years if we work really hard! Besides, these systems would be able to transmigrate themselves to new bodies over telecom when it becomes necessary!  

What next?

Some of you may study the feedback contest mentioned on the Chatpat website and perhaps participate in it.

Some of you might want to do projects related to this whole area. I will keep all this in mind when I plan my future blogposts.

Meanwhile, many of you may not agree about AI not needing feelings. Would it not be good for them to have empathy? And perhaps, curiosity? Should they not have something like mental activity when they are not conversing with a human? Or should they be talking to each other, or “learning” through the Internet?

Delivering supplies to a submarine under water

I find it odd that spacecraft routinely deliver supplies to the International Space Station, while there is no way to deliver supplies to a submarine under water. Is it conceivable that an underwater drone could safely dock with an under-water sub and deliver supplies? This could be a ton of enriched air to manage an emergency, medical supplies, or food. Imagine a sub receiving a hundred kilos of fresh salad, after a couple of months under water!

Such delivery may disclose the location of the sub. Hence, this may be a risky maneuver in times of conflict. However, we have heard of under-water emergencies in peace time as well.

I do not want students to worry about trying to sell a solution to the navy! It is a job for a company. However, students can experiment with underwater drone technology and do a concept demonstration. You can visit Torpedo - Wikipedia and Torpedo tube - Wikipedia to get the general background. Many subs use torpedoes that are 533 mm in diameter and about six meters in length. They weigh approximately a ton and are driven by an electrical motor. They have a range of a few kilometres. The interesting thing is that they are fired from torpedo tubes. There is a torpedo room connected to the torpedo tubes. There are doors at both ends of the torpedo tube. In principle an underwater drone should be able to dock into a modified torpedo tube! The supplies can be taken out through the torpedo room.

It might even be possible to put in a sick or injured crew member in the drone and send him to a nearby ship. These possibilities would be particularly valuable for stricken submarines that are not able to come to the surface. But, alas, I wear a 42-inch shirt, and therefore won’t fit into a drone docked inside a torpedo tube!

Now for the concept demonstration. If your college is near a waterbody, you could think of building half size replicas of torpedo tubes. You can then build underwater drones and demonstrate that they can home into a docking tube.

The Hotel on TK7, L4: The Next International Space Station

 

TK₇ is an asteroid that was discovered in 2010 by the NEOWISE team of astronomers using the WISE space telescope. It is about 300 Meters in diameter and is a part of the world’s most valuable real estate! Why? It is easier to reach than the moon, leave alone Mars. It’s orbit round the Sun is close to that of the earth and is gravitationally synchronized to the L4 location of the earth. It is astronomical convention to call asteroids at the L4 and L5 points associated with a planet Trojans. So, technically, TK₇ is a Trojan.

The mathematician and physicist Leonhard Euler had shown in 1750 that there are three points L1, L2 and L3, associated with a planet circling a central body like the Sun. The scientist cum mathematician Joseph-Louis Lagrange had shown in 1772 that there are two more points L4 and L5. Objects at or near these points are relatively stable there. Visit What are Lagrange Points?

We have L4 and L5 points on the earth’s orbit around the Sun.

A spacecraft headed to TK₇ will need much less fuel than one headed to Mars. A spaceship going to Mars would have to fire its rockets and burn a lot of fuel to do a soft landing on Mars. A spaceship headed to L4 or L5 would not need to fight any strong gravity. Gravitational force exerted by the Sun near L4 or L5 is only 6 mm/sec²! Synchronizing a spacecraft’s orbit with that of TK7 would not require huge amounts of energy.

The return to Earth from TK₇ will also require much less fuel than a return from Mars. Gravity at its surface is twenty thousand times weaker than that of the earth’s gravity we live in.

Why is 300 M diameter rock a valuable real estate? Because, living on it would be much easier and safer than living in the current International Space Station. You can live, say, 10 meters below TK₇’s surface, very well protected against cosmic radiation and micrometeorites. Temperature management would be a lot easier. Space available for living and for work would be a lot larger.

Who would want to live there? Scientists interested in studying the universe, for instance. They have had the James Webb Telescope working from July 2022 at the Lagrange Point L1 in the earth’s shadow. It is a very complex telescope, and if some part of it fails, there is no way to repair it. On the other hand, if a telescope is built on TK₇ a resident crew could repair it easily.

The 300-meter diameter TK₇ would have a surface area of about 60 acres if it is a smooth sphere though it is unlikely to be a sphere. However, gravity on its surface is so weak that we should have no trouble building big structures all around it. In course of time, we could even give it a 400 Meter diameter outer shell in the form of a smooth sphere! Building materials that weigh a ton on earth would weigh a mere 100 grams on TK₇! Elevators, if any, would need power mainly to cope with inertia, as weight would be negligible.  

Other possibilities are of modifying the rotation of TK₇, so that one side always faces the Sun and generates huge amounts of solar power. The other part could always face away from the Sun and can house big telescopes to study the universe at various wavelengths. Of course, there would be a need for radio telescopes as well on TK₇, provided we have tight control on electromagnetic noise.

How about air and water? Recycling them, monitoring them, and keeping them unpolluted, will be major challenges. Water and air will also escape the meager gravity of TK₇ if there are any leaks.

Building and operating a station on TK₇ would require international cooperation. This would be a unique project which would require states of the world to cooperate on a huge and expensive high technology project.

Would the scientific value of such a project alone persuade member states of the UN to contribute its cost? Would the project be sustainable without a source of revenue?

One option for a revenue stream would be to allow a certain percentage of facilities on the trojan to serve tourists for a few weeks each. That is why this article is titled “The Hotel on TK₇”. Wikipedia mentions 56 million as the number of millionaires in the world. Perhaps one could attract 10,000 of them per year to visit “The Hotel on TK₇”. If they stayed for an average of 7 days each, we would need about 200 bunks on TK₇. If they paid 2 to 3 million dollars each for the trip, they would contribute a reasonable amount. Would the astronomers want this crowd around?

Mining for rare elements is another possibility, but mining on TK₇ may not be compatible with other activities on it. Is there a sufficient tonnage of asteroids orbiting the L4 point to support mining activity? Ideally, mining should be coupled with manufacturing. This would make it worthwhile to mine even not-so-rare metals such as iron. To go lower down in sophistication, we can even manufacture prefabricated hollow blocks for use in constructing buildings on Mars. The manufactured products should be exported to Mars rather than to earth. The low cost of transportation from L4 would make Mars a very attractive destination for goods manufactured around L4.

It is possible to create a semi-permanent facility for asteroid mining to be located around L4, but not on TK₇. Potentially interesting asteroids could be brought to this facility by automated asteroid lassoing spacecraft. The miners who run these activities could be based on TK₇; they would make trips to the mining facility whenever necessary. However, human effort involved in space-based mining and manufacture should be minimized. Processes should be automated as far as possible because human presence in space is so expensive.

The biggest attraction of building a station on TK₇ is that it would be a valuable steppingstone to a permanent station on Mars. The scale of the effort would be smaller, and the costs and risks involved would be much lower.  

TK₇ is not the only trojan that we should consider. The earth has a larger trojan linked to its L4, 2020 XL5, designated as a minor planet. It is 1.3 KM in diameter, making it much heavier than TK₇. XL5 may not be as attractive as TK₇ for staging Mars expeditions, as its orbit takes it well away from Mars. In its nearest approach to the Sun, it gets closer to the Sun than Venus. Chances of finding water on it may be low.

There are several trojans in Mars’ orbit, and two are big: 5261 Eureka, trailing Mars in its orbit is 1.3 KM in diameter. 2011 UN63, also trailing Mars, is 560 KM in diameter. Setting up a base on one of these would be easier than setting it up on Mars.

Careful study and analysis may show the advantages and disadvantages of these trojans for staging a Mars expedition. Ultimately, I suspect that “local” resources would matter a lot. For instance, the presence of a thousand tons of water or ice would be a big attraction.  

We would need a new breed of robotic spacecraft to do the necessary investigations of several trojan asteroids. The Japanese have established a lead in creating such exploration spacecraft. Visit the Hayabusa Page

Reducing the loss of Cellphones using a watch alert

You might have read this news item:

https://www.indiatimes.com/worth/news/how-a-lost-iphone-led-to-warren-buffett-investing-billions-in-apple-569497.html

It talks about a friend of Warren Buffet, who lost his iPhone in a taxi and felt very bad.

There is a simple way to reduce such losses. Assume that the owner of an iPhone is also wearing an Apple watch. It should be easy to arrange for the watch to alert the owner when he moves some distance away from the phone. Loss of the Bluetooth signal from the iPhone can trigger this off. ”Setting” can offer the owner the choice of having this alert on, or turning it off. The watch display can show if the tether is on or off. See also my earlier post related to this topic:

Admissions to IITs and the IISc

We, in India, are usually concerned about marks and entrance examinations.  Lakhs of applicants take the JEE (Main) test and those who get a specified minimum in that test take the JEE (Advanced). Finally, the top 10,000 rankers from the JEE (Advanced) get admission to IITs. There must be a few countries where such severe competition exists. Is there a statistical difference between those are in the 9900-10,000 ranks and in the 11900-12000 rank band? I doubt it.

That is not the end of the story. What do the tests measure? I have heard skeptical comments from many academics about how the exam-coaching industry runs circles round the system!

I was worrying about my daughter’s studying for the exams when she was in the 12^th Grade. “Do you want me to get marks, or get an education, Daddy?”, she asked. The professors know the difference. One of them, from the Indian Institute of Science has written a short article on Linked in which is essential reading for all those interested in the field of higher education.

Software to Make Highways Safe

 Suppose that a Jumbo jet crashed every day in India, killing all passengers in it. A similar number of deaths occur due to road accidents every day (377 deaths/day, or approximately 137,605 deaths/year). The country is not able to do much to reduce the number of these accidents.  I believe that our engineering colleges should do R & D to reduce the number of road fatalities. I will offer suggestions in this article. I hope they will trigger thinking and discussions. 

Reduce Speeding on Highways

India has made FASTags mandatory for highway users https://www.npci.org.in/what-we-do/netc-fastag/product-overview  This automates the recording of vehicle’s license-plate numbers and the time at which they cross any toll gate. In each case, the distance to the next toll road is known. Therefore, any vehicle exceeding the speed limit between two toll gates can be detected easily. All we need is Internet connectivity to each toll gate. This could be through a landline connection or through a cellular connection. Procedure-wise, rules can authorize the police to seize any over-speeding vehicle unless the driver pays a specified fine on the spot. 

An app running on a PC or even on a cell phone can alert the staff at a toll gate. How many lives would this project save?

Highlight Fatality Sites  

A high fraction of vehicles have someone carrying a smartphone equipped with a map application. We can work with the app service provider to maintain and utilize a nationwide database of road fatalities: locations in which one or more lives were lost within the previous 30 days. As any app user approaches a fatality site the app can indicate this in a suitable manner and give details. The text should be written for the purpose of making users aware of the risks in that segment of the road.

Enabling every road user to be a safety warden  

We see dangerous behavior on highways. These include trucks standing on a highway blocking a lane, vehicles doing illegal turns and road crossings, and vehicles not having the required lights on. Vehicles, usually two-wheelers, running against the traffic. Rarely do we report such problems and provide location information. An app can be developed to work with a map app. The map app could display a red disc or some such prominent icon all the time it is being used. The user should be able to use the icon and activate a reporting mechanism. This should automatically report the location. It should also enable the user to take a photograph optionally and add a short written text. The reporting user’s identity should be protected by encryption but should be available to a court if it is considered essential. The app should not require the user to stop at the place where the risk is present. That location should be identified as one where the user activated the reporting mechanism. The app should allow the user to complete the report within a specified time from the moment the reporting mechanism is activated. 

In conclusion, reduction of risks and fatalities is an essential objective in engineering. Technology can reduce road deaths by at least 25% within the next two years. That is, technology can save over 30,000 lives per year.
