Some are probably being set up for retirement. I wouldn't feel too bad. You should probably be more worried about yourself.

Makes me nostalgic for when I read Coupland's Microserfs in the bookstore the month it came out and thought, this... finally, people I could feel less awkward working and being myself around, weirdness and all.

Tech is nothing like that now. Guessing a lot of people will find earlier retirement tempting with so many skills to keep up with now and AI rooting out personalities and ages subtley in the HR pool.
