Some of the time 20 years experience feels like 4 years experience repeated 5 times with different buzzwords. The same screw ups, the same lack of understanding from missing the same point, the same management wish to do SEO and security later. Or to budget 2 weeks for bug fixing.

All that experience can help a lot. It's far from dead. We can even have the same emacs vs vim argument that happened in 1990.
