I think he was getting at something about industry language preeminence not changing much every 10 years. C in the 80s, C++ in the 90s, Java in the 2000s, QBASIC in the 2010s. Not that the languages themselves take that long to change internally.
I threw that last one in just to make sure I was illustrating the point and not trying to be historically accurate or trying to predict the future.
Would be ironic if QBasic came back. That is what I wrote my first real program in. (I made that game where the snake eats the apples and grows longer. Only mine had cheat codes and teleporters and stuff!)
