Without the experience of making and supporting such tools, you'll never acquire wisdom, or many useful skills. Thought.py is maybe my 4th note-taking system, simpler and more precisely what I needed than any previous. Practice makes perfect. Doing nothing makes nothing.
> Without the experience of making and supporting such tools, you'll never acquire wisdom, or many useful skills. There's nothing special about those specific tools. Instead, you'll acquire the wisdom and skills from the experience of making and supporting different tools. Ideally tools that don't already exist thousands of times over.
The point is to make your own version of a thing; it doesn't have to be one of those few I listed. To see that some other design or implementation doesn't satisfy you, and analyze why, and do it "right". You can only get that by writing something you can compare to something else.
If you do invent a thing for the first time—which you won't—it would be terrible. It'll take many iterations, your own or more likely someone else's. That's how Human tool-making works, from the first half-assed rubbing-sticks-together fire to nuclear weapons (the first Atomic Bomb was not the best…)
And to a certain extent, I don't consider people incapable/unwilling to do this "programmers". Merely typists.
