The truth is, I barely think about these things as “apps” (I have no intention to distribute them). They’re artifacts of me making my computer do stuff for me, the way I want it to. As a Unix nerd, I’ve always been able to do this, in the language of the command line. Now, it’s just as easy to do that kind of work with graphical interfaces.
The future's gonna be wild for anyone who simply cares (even just a little bit) about anything touched by software (which means all the things).
