My hot take is that AI is a multiplier. Software engineers skill can be measured on a scale from -10 to +10, where 0 means you introduce as many bugs as you solve, or something along those lines(this scale is loosely defined, don't think too much about it)

Any engineer who's skill value evaluates below 0 on my scale, ends up with a large negative number when they use AI. Anyone with a positive number ends up with a large positive number.

The extra bugs you're seeing are from devs on the wrong side of 0 on my poorly defined scale.
