The arguments put forward are very weak, in my opinion. It made me depressed, not hopeful, as in: if this is all we have left, things are becoming desperate indeed.
To elaborate, if coding is like art, it's the worst art there is. It's far closer to something like legos and the satisfaction you get from completing a noteworthy build. Maybe that's the writer's point - yes it's still worthwhile, in a purely hobbyist sort of way.
I find the "coding helps math" argument to be similarly weak. Yes, it certainly helps with algebra, but overall I would argue the coding flavor of math largely helps more coding type of math. It's a strange type of math with loops and rules and conditionals that wouldn't be mainstream if software wasn't so mainstream to begin with. When you pull back the covers, the argument sounds more circular than something with true meat on the bones.
