Each time I visit some physical betting shop in my country, I usually observe how some elderly people make use of computers. I live in a country where most people 55 years and above don't have basic computer education. Many of them cannot use the mouse, keyboard, or other parts of the computer. This might be because most of them have not been exposed to computer education.
However, the introduction of online betting has forced most gamblers in my country to learn how to use the computer. It is now common to see some elderly people using the mouse and keyboard effectively. Most of them have never attended any computer education class but learned through observation. Others might have gone through some level of training from family or friends. I am sure many of them wouldn't have learned anything about the computer if not for online gambling. What are your thoughts?
People who are gambling online are probably doing already something else online, like messaging trough apps, and contacting their grandchildren who are often so naturally tech-savvy they prefer to communicate via apps then via phone. Then there are bank apps to pay their bills with. Old people that i know don't really want to go physically to banks anymore, and if they have problems with their computers, the helpdesk comes to visit them if needed.
And if you are talking about the browser interface, it's more exceptional then not for them to have a facebook or other kind of account to be in contact of their "group" of people (like hobby, or what ever that group is). That doesn't make them good with computers, but i can't see why gambling would either. Old people can get lonely and when they see they can get into communities in the internet, it's really addictive for them.
And people who avoid all online activity are starting to be such a small minority, that they really aren't a problem to anyone else then some services that need to have mortar and brick offices designed specially for them.
So i don't really think that gambling specifically from all things is in any key element when old people learn about computers. And again, gambling online isn't about computers, it's not about software either, but about very specific sofware, as in browser user interface of a casino.
