You know what? I worked for a large tech company (unnamed) a few years ago. There were tons of old people who viewed the younger folks in contempt. It can happen both ways.
Absolutely; I made my entry in to Fortune XXX level companies by way of my tech skills doing basic things with Word that SVPs & MDs couldn't be bothered to learn, yet were critical to actually driving business. The hostility was palpable sometimes. There were a slim few senior staff workers who genuinely expressed gratitude for filling in for a very large, important skill-set they simply didn't grasp or feel compelled to learn during their professional careers. Being on the same team, I appreciated that, certainly not put-downs and disrespect during the process because of my seniority.
