In my many years as a DBA/developer, I have learned that understanding
the low-level stuff, even down to the CPU behavior, allows debugging of
problems much more efficiently, to the point where it looks like magic
when you can quickly point out the problem. Also, the low-level stuff
rarely changes, so once you understand it, you can use it forever. The
big problem is getting people to see the value in learning that stuff
when they don't have an immediate need --- curiosity helps with
motivation. :-)
