why do you think older people aren't that familiar with technology?

I am an older person.

I have written computer programs and even learned a little about building computer circuitry.

I am familiar with the technology that interests me. But I do not have the knee-jerk reaction of pursuing every new thing that comes along.

I suspect that a lot of older people have seen so many new fads come and go over the years that we are not so easily wowed by everything that becomes trendy for awhile.
