just wondering, given the above average "geekiness" possessed by many who post here, in 40-50 years when we're all much older and winding down our careers, will we still be able to keep up with technology then? Will we have no problems using an iPad 50, or whatever machine is out there? I remember my 80 year old grandma who saw my iPad and had absolutely no idea what it did, or the significance of what it was (while at the same time, some kids are even selling their kidneys for one), will we end up like that or will we be able to keep up our technology sophistication as we get older?
