I think it depends on what niche you're in. I'm in the storage business and while not everyone, but quite a few of the people in my group would not be afraid of running a disaseembler, or talk about branch prediction, or unaligned integer access. `likely` and `unlikely` are very common in the code, and so on. AFAIK linux kernel people are very similar, and I assume a few other niches of system programming as well.
