You may be right of course but it is an interesting point.
I might add, that as you get older, finding technical jobs gets more difficult but management roles are easier. I employ techies now and am ashamed to say that I have to force myself to interview the older ones because very few of them still have the passion that the young ones do, even if they are less likely to make mistakes. Some do still have passion and make excellent employees but I can understand why some people would pass over my rather extensive technical CV when they see my birth date
With your low Slashdot UID, I guess you have been in this game a while too. I'd be interested how you see your own future panning out in this respect.
