The dirty secret is all the people talking about shipping 4 features a day etc are just lying about reviewing anything. They don’t review it at all.
The review comes at the end, though I truly believe this will go away as well. Agents will also get better at review until they're good enough that no one will want to do it anyways. Good enough is good enough.
It's like saying that you code reviewed faster just because someone else also reviewed the code, that's not how it works.
Its nice to not have to care about nits and other things that we don't have lints for though, so that's useful.
