The LLMs are wicked fast at reviewing code
That’s because it’s not actually reviewing the code, rather just producing text that statistically looks like review comments.
So it does look vaguely useful, e.g. if code has null checks, review comments usually won’t ask for them to be added, but it’s never actually reviewing, or understanding, or reasoning, or anything else people claim.
It’s like an actor playing a doctor in a TV show, they’re not actually diagnosing patients, they’re just following a script that looks like it.

And it’s also not like the hardware is improving much either, we’ve effectively hit the wall performance wise with processors and RAM.
That’s literally what all these datacenters are for, we can’t scale the individual computer performance up, so instead we build more and more of them.
