What the fuck are you talking about, thats not what the poster said, you've done weird contorting of what they said to arrive at the question you are asking now.

While some tests make sense, I would say about 99% of tests that I see developers write are indeed a waste of time, a shit tonne of devs effectively are writing code that boils down to

Assert.That(2, Is.EqualTo(1+1));

Because they mock the shit out of everything and have reduced their code to meaningless piles of fakes and mocks and arent actually testing what matters.

Do you do code reviews in meetings?

Honestly often.. yes lol

Do you think testing and reviewing code was a waste of time before “AI”?

I would say a lot of it is, tbh, not all of it, but a huge amount of time is wasted on this process by humans for humans.

What the poster was getting at is a lot of these processes that USED to be INEFFICIENT now make MORE sense in the context of agents.... you have vastly taken their point out of context.
