Again, I would suggest that it's not all old people who do this. It's just that the old people who like to do this also like to spend their entire days posting comments in forums like this.
Most old people I know continue to learn and adapt to the changing world around them. They try to keep up, rather than getting left behind.
The simple reality is that these forums create an image where people who can't adapt to the changing world are over-represented, while people who are busy learning and adapting don't waste a whole lot of time here.
