I am inclined to agree with Peter and Jennifer here. Maybe the people you meet in your line of business need your help to use computers and the internet but I wouldn't go thinking they are representative of all folk over the age of 40, far from it. I have to guess your misconception might be at the root of why folk in your social bracket can't imagine folk at my age (60) for example being able to still run rings round you probably without you even noticing, because we have vastly more experience of both life and computer and internet technology than you do.

And besides, I don't think it can be very clever, to be writing so disrespectfully of who must be either your clients or folk you work with. Either way, I don't see them offering you much support in your ambition to become a one person billionaire company :)
