His argument also necessarily presupposes that you're never going to use a debugger to root out latent bugs, that is, you're only using a debugger because you've just written some buggy code and and you're trying to figure out where the problem lies. Which is silly. There are bugs in the kernel right now, there were bugs when that was written (he even alludes to it, but seemingly fails to understand the implication of it), there will be bugs introduced in the future, and someone at some point might like to find those bugs. Some of the best "What is the worst bug you ever encountered?" war stories are cases where people end up narrowing things down to a bug in what they were previously treating as bedrock.
