Honestly, I feel like ageism as an industry social thing doesn't properly reveal the details behind why businesses make the decision to get rid of or stay away from the greybeards. In reality, greybeards are harder to manage, command higher salaries, and don't put up will bullshit. Basically, managers want a young pliant fool willing to spend three years putting in 60-70 hours a week before he realize he is fucking himself over. So in this case, I would argue ageism in the industry is mostly about money and business-culture, not techno or geek-culture. One lesson I learned early in life was to listen to the old timers, It applies here as well, we spurn the oldies at our peril, for they learned lessons we have forgotten and are trying to resolve.
