There are a lot of times where a low-level understanding of Computer Stuff lets me easily get problems in simple stuff. Like if I see a year that's 1969 or a number that's in the negatives and around 4 million, I know some kind of overflow happened and can work from there to diagnose the problem. I don't know the right balance, though. I know all this stuff because you just had to if you wanted to do anything with a computer beyond simple office tasks.

Even advanced stuff has nice interfaces these days. My new laptop with a dGPU comes with software that has an overclock toggle and some guidance on how to get the most out of it, warnings, etc. That's a long way from editing files to make HIMEM.SYS work so Wing Commander would run.
