Simple turn-based games such as chess turned out to be too far away from anything practical and chess-engine-like programs were never that useful. It is entirely possible that this will end up in a similar situation. ARC-like pattern matching problems or programming challenges are indeed a respectable challenge for AI, but do we need a program that is able to solve them? How often does something like that come up really? I can see some time-saving in using AI vs StackOverflow in solving some programming challenges, but is there more to this?
The US doesn't have the people to do the actual manufacturing. I saw a video recently explaining how sectors like the military, construction and the automotive industry each have 100K+ positions that they are unable to fill. A return to manufacturing adds to that shortage.
Apparently there's some 7 million young men of working age that are...missing in action. Self-isolated, gaming, addictions.
In construction, for every 5 people that retire, only 2 enter. And it's been like that for over 10 years. The people aren't there nor is the motivation.
I'm sure you'll have Apple investing in a mega plant where 50 educated people push some buttons though.
