Re: 80-20 rule?
If you are talking resourcefulness and ingenious ideas, Computers are more creative than humans, they do not have the same limiting assumptions. This has become clear with chess engines. None of the grandmasters today toil away hour after hour trying to come up with ideas. They just have the engines come up with ideas to try in whatever variation they want to play. Chess has become my prep vs your prep, which means my computer's ideas vs your computer's ideas (and what we can remember of that prep). Before computers were GM strength, chess was dying, boring cowardly draw after boring cowardly draw. Since then it has been one crazy idea after another. And what is more, they are incredibly brave. They are what we would like to be: strong, fast, accurate, creative, brave, patient, and long suffering as well. Much of that was born of criticism. We said "But it can't do this...", so programmers worked and it can now do whatever better than the humans often embarrassing better than the best. And in bad situations they are extremely resourceful and scrappy...they do not give an inch they do not have to...no quitting, no loss of concentration while winning, letting a player back in the game, they just grind you to dust.
There are just a very small number of things the engines can't do better than the strongest postal grandmasters. Mostly it is about things that can be approached in a thousand ways but it is clear to the human they will not work because one of several things is required to change the outcome...and the human can identify those while the machines can't yet. So it is mostly recognizing when something is impossible/necessary, it just keeps looking at the billions of possible continuations and permutations. So whee! We are best at quitting and recognizing when some effort is useless. Sometimes that is useful...but it is not a huge thing to boast about.
Will that save your job? Doubtful.
