> You either spend brain-time on memorizing the intricacies of a lot of prebuilt tools

I suppose another piece of evidence about how this is a personality thing is that I hate having to learn specialty tools. They're limiting in that typically, they only exist on certain platforms, and they often specific to certain languages, so knowing those tools often doesn't help me generally. (Libraries and the equivalent count as tools here, too.)

So I make it a point to not grow a dependency on them even when I use them. I very much prefer to focus on skills that I can leverage widely.
