the old case tools
When I were a lad, back in the mid nineties, almost to the end of my post secondary education, and quite overwhelmed, CASE was the course I totally let go. I went back and did it in night school afterwards to finish. Just obviously a total waste of time why let it hold back work on more important things. But required, sigh.
The thing was, I was in the "Applied Artificial Intelligence" option. Sounded most interesting, and LISP and PROLOG were mind bending, but at that time literally any other option would have ended up more lucrative, sigh.
At the time I was convined that the way to artificial intelligence was through genetic algorithms and artificial life and I wrote about it, and dabbled in coding for it. I am still convinced. There has to be evolution, and there has to be a world to evolve in. At the time we could have simulated a world complex enough to evolve simulated single cell organisms, and worked on more complex worlds as technology evolved to evolve more complex simulations of life. Going from the megabytes of the time to the petabytes and exobytes of today we should be currently interacting with simulated lifeforms with the intelligence of not just a human, but of a human race. But we have gigabyte requirements for simple operating systems instead. Sigh.
But my big project was an "Expert System" for of all things appliance repair. Using this newfangled World Wide Web thing. A collaboration with the trades side of things. Using the right words it could sound impressive on paper and it got me through but it was obviously nothing to do with artificial intelligence, at least to me. It was a "useful tool", just like the best that the large language models of today could hope to be. Just like I turned out to be, toiling basically in the basements of office towers on the finance and inventory plumbing that I swore I never would, I got rid of accounting and statistics and kept all the wrong textbooks sigh.
A large language model can never give you anything that didn't come from it's training data. Aguably just like us meatsacks, but god damn that's a depressing way to look at it. When we can actually define the word conciousness, or "soul", then maybe on that hallowed day we can start down the actual road to simulating it. Currently not even anywhere near the ballpark, haven't even invented the bat or the ball let alone the stadium, IMHO.
