"It seems JS is getting really big lately, since everything is going to the web. But there must be something next that is just a leap different than everything going on right now." I doubt it. You'll just be compiling JS (or a JS descendant) down to a quantum machine or DNA or who knows what. Change is incremental. People talk about the rapid pace of change in technology, but if you learned C in 1985 and no other language for 25 years, you'd not be very far behind right now.
