The stability cuts to your pragmatic argument. Specifically, I keep getting student hires on my team that think the Java or the Python they used for school will cut it in the office. In large, it won't. JavaScript, similarly, has more online resources, but similarly, most are not helpful for modern use.

Depending when you made this argument, stack overflow was a great resource. But many answers for the languages you pick as pragmatic are not good answers for modern use. And it seems to be getting worse.

For the other, you are taking my evidence the other way, oddly. I would expect language to matter very little. Such that, pragmatically, it makes no difference.

That is, I'm not trying to prove people do better because of racket. I'm guessing to prove they do no different because of python. Indeed, I enjoy lisp. But I doubt it is truly easier than most other options. Just so I doubt it is truly harder than most other options.
