As an essayist I've found the abstraction of thinking in terms of "lisp" being about "list processing" to be very helpful when reasoning about and abstracting ideas precisely.
Lisp can have almost zero syntax, so can last a long time and be picked back up quickly, I've found.
This doesn't necessarily mean lines-of-code is the most productive immediately; as much as there is resistance to it from current (i.e., 2018March17) mainstream programmers, hyperdimensional programming (i.e., 2D+, and higher in VR) like with Unreal Engine 4's Blueprint, are likely going to win out with pure advancement of results, perhaps (that is, creating effective art quickly).
Imagine finessing functions of different shapes in VR, rather than lines of text code.
From what I've read (which isn't hard to find, but I'm mobile right now), the danger of VR for kids is not an issue, and in fact can actually more quickly bring to attention if they have a biological issue (like more quickly reveal if glasses would benefit them).
I'm running High Sierra on a 2012 MacBook Air and haven't noticed any slowdown. Heats up if I run a lot of things at once, but individual apps seem fine.
If Teslas drive themselves and other EVs don't, are they a comparable car?
