>Complaints of AI are like a form of friction that eventually goes away.

This. Already there is evolution in AI-related comments here.

For example, a year ago they often featured remarks like "I know AI when I see it: here are unmistakeable 'tells.'"

Then there would be a lively back-and-forth about the validity of the stated giveaways.

Such "How I know it's AI"-type comments no longer appear.
