As someone who fears ageism and my role as a hacker in light of the aging process, I am taking his post to be a beacon of light and hope, not anything resembling a 'douche'.
Trust me, anyone who perpetuates ageism is somewhat misled. A diversity in the ages of employees is probably the ideal situation, because I can think of advantages/disadvantages the presence of a certain each age group brings to a team. On the other hand, if you find yourself losing energy/physical fitness and your abilities, its your prerogative to remedy that.
I'm a younger (~30) engineer who's enjoyed working with a few older engineers. I'd be interested in hearing more about what you perceive to be the relative advantages/disadvantages of each age group.
From direct experience: you can't group by age. Some older engineers are douchebags. Some are the nicest people you've ever met. Some are incredibly talented. Some aren't.
