This still surprises me.

Mostly around, at least the majority of 'stuff' I've worked on (both before and after the rise of coding agents) myself or others took enough time to make sure that anything done locally, if you run the tests locally, you're at least 90% of the way there as far as what CI/CD does.

I suppose the flipside being, most of those projects had less churn (i.e. one person was working on a service at a time, and we had good contracts between services.) Also, Our local boxes were way better than our CI boxes, so there was incentive to run locally versus waiting 2-10x the time for CI to run...
