And over and over time proves that, when you need it, ASM or C or generals system knowledge was handy. One example, I am not a "Windows" or "NT" guy, mostly working in various Unixes and Linux in my professional career. I had a client who had battered every resource trying to fix some horrible freeze/timeout in their application. So I rolled up my sleeves, first search " is there dtrace on windows", found some profiling tools, found the process was stuck in some dumb blocking call loop, resource was unavailable, and the rest was history.

So yeah i mean - who cares how it works - but also if you have experience in how things _do_ work you can solve problems other people cannot.
