I'm highly worried that you are right. But what gives me hope is that people still play chess, I'd argue even more than ever. People still buy paper books and vinyl records. People still appreciated handwritten greeting cards over printed ones, pay extra to listen to live music where the recorded one is free and will likely sound much better. People are willing to pay an order of magnitude more for a sit in a theater for a live play, or pay premium for handmade products over their almost impossible to distinguish knock offs.

How transient depends on the problem space. In chess, centaurs were transient. In architecture or CAD, they have been the norm for decades.

Agreed. But I don't think the time scale will be similar.

Chess is relatively simple in comparison, as complex as it is.
