I think a big part of that divide is between the people who are inherently limited by other factors on the rate of change they can implement.

If I'm being snarky - the people who are happy to run without reviewing the code probably mostly are able to because there isn't significant value attached to it downstream. Not many stakeholders, not high value transactions, not complex downstream integration or impact. And yes, in their friction free lives, AI can massively accelerate things far beyond what it can do for the rest of us. But don't infer that applies everywhere else where those assumptions don't hold.
