My guess is that world would be indistinguishable from ours. There is nothing wrong with Ruby.
My question angles more toward learning functional programming first, and I doubt it'll ever happen at bootcamps (though - my understanding is that's exactly what happens at Berkeley/MIT with Lisp/Scheme in CS101 (I'd argue with decent results)) - so it's very much a hypothetical.
Is it decent results because of functional programming? Or decent results because those colleges select for the people who generally have the most intellectual aptitude and you could have them write Cobol on tape for CS101 and they'd still be great
I heard that it’s a special form of torture, since those CS programs must be hard, but I don’t really buy it.
