The amount of time I spend going back and forth between the implementation and the test cases to verify that the tests actually fully cover the possible failure cases alone can easily exceed the time spent writing it, and that's assuming I don't pull the branch locally and start stepping through it in the debugger.

The idea that AI will make development faster because it eliminates the boring stuff seems quite bold because until we have AGI, someone still needs to verify the output, and code review tends to be even more tedious than writing boilerplate unless you're speed-reading through reviews.
