I think it's fair to say that this is the way it's always been. In 1990, you couldn't hack on an accurate fluid simulation at home, you needed to be at a university or research lab with access to a big cluster. But then, 10 years later, you could do it on a home PC. And then, 10 years after that, you could do it in a browser on the internet.
It's the same with this AI stuff.
I think if we weren't in the midst of this unique GPU supply crunch, the price of a used 1070 would be about $100 right now -- such a card would be state of the art 10 years ago!
