Sure, still, 20 years on. Not dogmatically so to reach some coverage goal, but anything with real logic, yes. I don't test-drive React components, for example (instead the goal is to get all real logic out of them).

Benefits--not pushing logic defects gives me more time to invest in other important stuff; I end up with tests that document all the intended behaviors of the stuff I'm working on (saves gobs of time otherwise blown trying to understand what code does so I can change it safely); I'm able to give a lot of attention to ensuring the design stays clean. Plus, it's enjoyable most of the time.

"They incur technical debt and bugs at the same rate as other code." Not at all true.
