The inability to keep up with new technologies is something that ended even by my own generation (I'm 30 now). I can't think of anyone under 40ish that hasn't been able to grasp some new concept.

People like myself who have been programming or working on computer tech stuff almost their whole life would have learned how to consume and adapt new technologies simply as a way of life. I think the whole ageist concept is out of date already and will just continue to deprecate even more as people who grew up with changing technology and embraced it will become the majority in the field.
