This but unironically. Of course review your own work. But QA is best done by people other than those who develop the product. Having another set of eyes to check your work is as old as science.

That is often how software development has been done the past several decades yea...

Not to say that you don't review your own work, but it's good practice for others (or at least one other person) to review it/QA it as well.

You're making a false equivalence between a human being with agency and intelligence, and a machine.

Yes. That’s not a best practice. That’s why PRs and peer reviews and test automation suite exist.

I mean there is some wisdom to that, most teams separate dev and qa and writers aren't their own editors precisely because it's hard for the author of a thing to spot their own mistakes.

When you merge them into one it's usually a cost saving measure accepting that quality control will take a hit.

Yeah, someone should invent code review.

Uh, yeah, thh hi is has been considered bad practice for decades.
