The .COM bubble was more than a divot because .COMs in so many industries employed so many people. There was amazon.com, but also pets.com, lowermybills.com, gateway.com. But if our economy somehow loses access to AI (rationing due to wartime efforts? sabotage by a foreign nation? simply not enough grid power to turn them on at the price people are willing to pay?) I would probably need to hire more coders to get the equivalent work done.
