> there is plenty of work for those who are old and mediocre. ;)

Agree with everything you said including this one.

The point I was trying to make isn't that there won't be plenty of work for us. There always will be existing code to maintain and update.

The point I was trying to make is that development is rarely done in isolation, so you'll likely have to work as part of a larger team.

It's extremely likely that the majority of that larger team will be much younger than you and will be playing an exact copy of the JavaScript games you're playing now, but with ShinyNewLang.

So my question was - when that happens, would you, with the experience you will have by then, be mentally OK playing those games?
