I don't understand what kind of evidence you expect to receive.

There are plenty of examples from talented individuals, like Antirez or Simonw, and an ocean of examples from random individuals online.

I can say to you that some tasks that would take me a day to complete are done in 2h of agentic coding and 1h of code review, with the additional feature that during the 2h of agenti coding I can do something else. Is this the kind of evidence you are looking for?
