Languages don't die. That's a misnomer. They have long tails of diminishing use and no junior programmers entering the space. If you're one of the experts in the language left around, you can make a shit load of money.
And the jobs are rarely worth the stress of picking apart the terribly designed, chock full BizDev rushed ads-on features due to foolish promises, and a manager that's stressed out due to how few experts they're are that's going to try and micro-manage you because his skip-level is breathing down his neck about when something is going to be fixed.
