We're getting some practical multi billion dollar products this time like self driving cars. That didn't happen the first time around - you couldn't build that sort of stuff with the 1970s computers.
That is true, but those products have little to do with OP is talking about. Self driving cars are using nothing more than a calcullator. A very sophisticated one, for sure, but it a calculator nonetheless. It is dubbed "AI" because it sounds sexier.
Yeah but the AI winter was mostly a period of low funding for AI due to disappointment at the research in the 70s and 80 not producing useful products. No one then was expecting human level intelligence but they were hoping to get some return on investment.
