> The only tangible thing we have to show is software development, and some other fairly niche jobs, have changed _a bit_.

There is zero evidence that LLMs have changed software development efficiency.

We get an earth-shattering developer productivity gamechanger every five years. All of them make wild claims, none of them ever have any data to back those claims up.

LLMs are just another in a long, long list. This too will pass. (Give it five years for the next gamechanger.)
