CI systems are awesome when they are working.>writing good tests is really helpful for me
I'd wager it's partly generational. If you came up in the agile world, then you likely see the upside but not the down since there's no reference point for the latter. Because, of course it's cool that these CI build processes kick off at commit points (or whatever). And, of course, the near instantaneous feedback that something is broken is more efficient than awaiting a nightly build. OTOH, we were much more cautious about the code we checked in because the stakes were higher and you didn't want to be the heel who broke the build. "Move fast and break things" was not a thing. Instead, "be thoughtful about what you're claiming to be good code" was the ethos.
But, this is not an argument about efficiency or whether these things can be made to work. The argument is about the cost to the developer of all of these things in sum, and the philosophy they serve.
Likewise with TDD. I'm not arguing that tests don't help code quality and I've heard others say they like writing them. YMMV and all that. But, it's more load on the developer and I've definitely seen it overdone.
So, again, without the reference of a "saner" world then you don't likely have the context to fully appreciate these costs. I see them, though, and frequently hear them when people complain about burnout. It's not CI/CD or TDD or whatever that's the problem. It's that these things are frequently used less as tools and more as the instruments of a philosophy that plugs developers in alongside them as just another part of the never-ending pipeline.
