This reminds me of the Go champion who announced he was giving up the game after a computer beat him.

It’s as if a runner were to give up running when beaten by a horse or a car. It suggests they may have had unexamined and perhaps somewhat strange reasons for doing the activity in the first place.

People have difficulty accepting just how significant their limitations actually are. We design our world to hide those limitations. As an example, it would be easy to make computer games that are unwinnable by humans because of our slow reaction times, low speed in general, and our cognitive limitations. But no-one makes such games, because few people would want to play them for very long.

The “terrible cost” in this specific case seems to be related to discovering that we were fooling ourselves about how good we were at software development.
