And who did they tell? Word of mouth sells hardware and 50+ people barely have 1-2 friends if any.
My 73 year old mother owns a laptop and a netbook, both of which she picked out on her own (and figured out how to use on her own).
She still works part time 2 to 3 days a week as a nurse anesthetist (earning about $50K a year).
And to close, she probably interacts with more people in a day than you do in a month and undoubtedly has at least twice as much residual intellect left than you were born with.
As I approach 50, I'd ask you to keep your smug youth centric comments to yourself. Personally I see no evidence that youth has any advantage in intellect and it certainly hasn't any advantage in wisdom or common sense.
