Surely you'd find something to discuss about one's previous twenty years of building software. Especially if the last ten years have been in the same domain. Somehow it all worked just fine before 2010 or so. Also, one's tolerance for silly things and short-term memory for useless puzzles don't increase with age.

You know you live in a clown world when memorizing nonsense makes one more employable than learning some front-end stuff to be a little more full-stacky.
