How AI Will Revolutionize STEM and Society

[Averagesupernova]

Why compare it with humans at all? Is it because of your understanding of the word intelligence?

You have a valid point. And the (in my opinion) obscure definitions cause some trouble when discussing it. Right now as far as I know human intelligence is the highest known, or at least recognized. What would you compare it to?

A number of years ago I troubleshot test equipment in a factory setting. Part of my job was to create flow charts to indicate what part of a circuit board the calibrator was to inspect based on a particular failure. Wrong part here? Wrong part there? Etc. What this amounts to is taking my intelligence and experience and condensing it down to a series of if-thens. The longer we manufactured a certain product the more detailed the flow charts became. After a certain time of course, there was a net loss in productivity by further detailing the flow charts. There was never a time when a troubleshooter such as myself was not required.

Even human intelligence can vary in unexpected ways. A friend of mine named Dave was a factory supervisor somewhere in Africa many years ago and he was assigned to get a wooden fence built along the back of the property.

He told the foreman of the workers that he wanted the fence to be absolutely straight and just to be sure he was clear, he showed the foreman a picture of a perfectly straight fence. The foreman assured Dave that the fence would be absolutely straight and then proceeded to build the fence in what Westerners would consider a crooked, slightly rambling line that probably never deviated from the center line by more than a foot or so but which to Dave was clearly NOT straight.

The foreman was flabbergasted that Dave did not see the fence as straight. Again Dave showed the foreman the picture and pointed out that the fence wasn't the same as the picture. The foreman insisted that the two fences were identically straight.

When Dave complained to the factory owner that the foreman was either obstructionist or mentally retarded, the owner just laughed and explained to Dave that for a African of that tribe, that WAS absolutely straight and you would never convince him otherwise.

You can argue that it was a difference in definitions, but I argue that it was a different way of THINKING about what "straight" means.

As far as I am concerned, doesn't the definition of straight or any word depend on how it is thought about?

Interpretation of definitions can certainly get us in trouble. But, for someone to argue that those two fences were identical is not playing with a full deck if they understand the definition of the word identical. I would have expected the foreman to say that they thought it was straight enough. The foreman did display a certain amount of intelligence based on the fact that (I'm assuming here) the fence was built in such a way as to do the job that he/she assumed it was meant to do.

What would you compare it to?

How about just looking at the utility of the machine without needless comparisons?

So what are you saying? It's pointless to compare a lowly thermostat to the intelligence of a normal human being? Intelligent enough is good enough? That doesn't make for stimulating conversation, nor does it give us any idea of how to proceed to make something smarter by having never compared one system with another.

And the latest fatale mismatch was caused by Boeing's software change to avoid a new FAA approval procedure for its 737 Max. As long as people program by the quick-and-dirty method, as long do I oppose automatic decisions.

That was human error, or malfeasance. MCAS could have been successful IF there was a way to detect inconsistencies of inputs from various instruments such that a fault (input error) could be detected and corrected. In the case of the aircraft's control system, there should have been a way for the system to know if an angle of attack (AOA) sensor was faulty (damaged). Left and right sensors should have been compared, and any difference/inconsistency challenged. The pilots needed training in over-riding (disconnecting) the system. Boeing engineering staff and management, and FAA (oversight), are ultimately responsible.

Error detection and correction is one area in AI needing attention. Currently, humans do the program and write the rules. Full intelligence requires learning from successes AND failures (errors).

In a wholly different area: A former colleague did a thesis on "Artificial Neural Network Modeling of Mechanical Properties of Seamless ___________ Tubing". I've seen similar works for various alloys. It requires knowledge of the alloy system, the sensitivity of mechanical properties (strain hardening and strain rate hardening) to composition, and the manufacturing process. Seamless tubing involves multiple mechanical reduction steps with intermittent thermal treatment (annealing), but annealing can be for recrystallization, or solution annealing, the latter being at greater temperature than simple annealing. The solution annealing temperature must be set in conjunction with time in order to prevent grain growth (this relationship will depend on the composition and level of cold work (dislocation density) in the alloy structure.

With respect to what is considered AI, did you know that there are at least 40 types of hammers.

Yes.

So what are you saying?

I say that we should judge machines by their utility and their risks. The methods (dumb/smart) that they use to achieve that are irrelevant.

A self driving car has benefits and risks, regardless of whether it uses AI or not.

I think machines of the future will be extremely capable. I also think that the experts will never stop debating whether those machines really have AI.

Game changer in the chess world! The extract below is from https://en.wikipedia.org/wiki/AlphaZero

DeepMind stated in its preprint, "The game of chess represented the pinnacle of AI research over several decades. State-of-the-art programs are based on powerful engines that search many millions of positions, leveraging handcrafted domain expertise and sophisticated domain adaptations. AlphaZero is a generic reinforcement learning algorithm – originally devised for the game of go – that achieved superior results within a few hours, searching a thousand times fewer positions, given no domain knowledge except the rules."[1] DeepMind's Demis Hassabis, a chess player himself, called AlphaZero's play style "alien": It sometimes wins by offering counterintuitive sacrifices, like offering up a queen and bishop to exploit a positional advantage. "It's like chess from another dimension."[9]

We asked our PF Advisors “How do you see the rise in A.I. affecting STEM in the lab, classroom, industry and or in everyday society?”. We got so many great responses we need to split them into parts, here are the first several. Enjoy!

If things run true as before, and I have seen no vast improvement in the correct forecasting of future trends from these areas, I see lots of money going in these areas but not much usable product coming out. I chose not to dwell on such predictions like back in the early 1980s when we were told the factory of the future would be a lights out manufacturing trend with only a few humans doing maintenance to keep the...

Pretty interesting read. I look forward to the next installment.

 

[Astronuc]

Yes.

Although I quoted your post, the last statement was not directed to you personally, but to the reader. I perhaps should have made that more clear.

 

[etotheipi]

A neat little demonstration in case you're bored...

 

[lomidrevo]

I am surprised that majority of advisors seems to be rather sceptical in teir opinions. Personally, I tend to agree with @bhobba, he mentioned some very interesting examples.

I think that by now AI should be part of rudimentary education (not the technical details, but the gist and scope). Many people don't seem to realize the role it has in modern societies and economies. News, politics, the stock market, social media, advertising, the internet; by now it's all driven mostly by AI rather than people. It's the reason why companies are trying to collect as much information about you as possible. You could say that it offers the power to have a customized Sith Lord for every citizen (per say). That is, manipulation is customized, as AI can utilize each persons situation and psychological weaknesses to optimize the effect it is able to have on your behavior. That's the big business aspect. And this is the thing everybody should understand so that we can have a conversation about the ethics and impacts. It should be combined with education in critical thinking and ethics. Everyone should know about what/who is trying to manipulate them and how.

Besides the role of AI in manipulating human behavior, advancements in autonomous robotics is set to further transform a number of areas: mining, war, espionage, space, manufacturing, farming, etc. The specifics about exactly how and when might be slightly uncertain, but overall and in general it's pretty clear and simple. The main factors that would change things are human intervention to regulate how AI is used, and competition between groups of people for control and domination. Besides that, if you look at the incentives and what is possible, you can get a good idea of what the future is likely to look like.

Personally, I think space is the big one. Modern AI is just about at the level where many of the key breakthroughs, envisioned from the beginning by people such as Von Neumann, are feasible. This includes interstellar space missions, massive industries in outer space, terraforming, etc. How far out these things are, is not clear. They currently still require extensive human input in terms of design and engineering. But at some level of achievement these things could be ramped up in scale enormously. We could, for example, launch a single automated mission to send probes to millions of stars, and then millions of probes from each of those million stars, and so on.

If you go further out, you can expect a time when science, mathematics, and engineering are also dominated by AI. In that case, it is relevant to wonder what role the human being has. The AI will develop insights, construct proofs, record observations, do analysis, pose new questions, maintain an awareness of the state of the art, etc. It will share this information in a distributed way in some non-human readable form. People would, by default, have little clues what is going on, but will notice improvements in technologies. We will likely act as managers giving approval on high level projects, while balancing trying to micromanage things we don't understand. Efforts will be made to figure out how to improve communication between AI and people, so that we can understand as much as possible in terms of what they are learning and doing, and participate as much as possible in decision making. Many proofs, analytic functions, and rationals, will be too large and complex to fit in human memory in order to be understood.

Humans have been manipulating humans from time in memoriam. Advertising of any type is has an element of manipulation from downright lies to psychology ("The Hidden Persuaders": by Vance Packard 1957). Now as you note it can target individuals. as always, caveat emptor. It isn't AI that is manipulating us it is humans.

The main factors that would change things are human intervention to regulate how AI is used, and competition between groups of people for control and domination.

We can regulate the overt use of AI but not the surreptitious use. How do you know an AI app is monitoring you? How can we determine what that use is?

What we do with AI is our decision at this time. It will change our behavior as we see benefits from its implementation. That change may expose us to or create problems heretofore unknown. Computers made the internet possible allowing us to expose our entire lives to the world if we choose making us vulnerable to crime and exploitation. But, then AI might help us. Perhaps we will develop a cyber Gort ("The day the Earth stood still") to monitor the web and protect us from ourselves.
