But are they women or men?
Both. I don't know the demographics of the entire site. Ladies don't always mention their age but I know one is close to 80 plus others in their 70s, several men who are 70-80+. It doesn't often come up and I don't focus on age, I'm more interested in content.
We were around at the dawn of the computer age.
My sister is 67, her husband is over 70. They are electronic junkies. They worked with mainframes early in their careers and migrated to PCs, tablets, smart phones, etc. My sister now does website design and his range of experience and computer knowledge is extraordinary. If I want computer or technical recommendations, I go to them.
My MIL, who would be 93 next month, worked in a data processing center and retired from that job twice. My mother had us do the initial set up of her computer (geeky kids) then she was off and running (she'd be 92). My husband is 68 and quite comfortable venturing out to the internet following his hobbies (and after seeing the toys my sister and BIL had, he has a long wish list). In 1973 I had to write a basic program as a requirement to graduate high school. Amazing to realize that was 45 years ago.
IMHO, being older today doesn't necessarily make one computer illiterate or unable to use them. For some it's a blessing as a way to connect to the outside world when their activities are restricted.
