Two questions from different perspectives. Why do colleges teach calculus, physics, and chemistry? Why don't they just tell students to "read the book, answer the questions and solve the problems? When done, we will test you." There are a lot of issues that involve money, perceived prestige, etc., but one of the main reasons colleges can't do that is that most text books are not written for self learners. You have to work hard to learn without the guidance of an instructor/tutor.
Today, we can use YouTube and other videos to help. But, consider what it would be like to have an expert system on each topic that is designed to help you learn? If you surf the net, you can follow links that you find interesting. Similarly, if you were learning and ran into difficulty, you could follow a link that would help you learn that topic. The current Covid virus has put a lot more demand on self-learning and has demonstrated how ineffective it is. Expert systems could be designed as study aids and as games to make learning easier and sometimes fun.
As more people get replaced by robots and automation, there will be a need to educate them in new fields. AI could help with that education. The traditional educational alternative is very costly. An additional alternative is to have people just wallow in ignorance while the world passes them by -- there was a Star Trek episode about a race of people who said: "We are smart" and who traveled through space acquiring technology that they could use but didn't understand. Our replaced workers could meet the same fate. A better alternative is to create educational expert systems to help them learn. I am currently developing an expert system in chemistry. There is an old saying: "If you want to learn something, teach it." I don't have anyone to teach, but I can learn a great deal by constructing my own system. In doing so, I have experienced first hand how poor some text books are. Two of my objectives are to solve each problem correctly and to explain, at any level of detail, what theories, factors, equations, etc. are involved. I have delayed indefinitely answering questions until an adequate NLP system exists. I choose Chemistry because we all know that "Chemists have all the solutions."
Any expert systems that have been or will be developed can be used as building blocks for more complex systems. Each such base system would be safe because it would not have any autonomous elements. We already have the knowledge, let's use AI to pass that knowledge on to others.
There may be a way to accomplish the above with deep learning, but I don't know enough about it to evaluate it adequately. In the meantime, I can fall back on what I do know and can learn.
Comments, criticism? As Dumbo might have said: "I'm almost all ears."
