Most people are saying a service where they pay you directly for talking to them.

I think a better use of that skill is starting some type of business targeting older people, using your communication skills as a selling point.

Start a grocery delivery service for the elderly, for example.  Sure, Amazon will deliver your groceries, but will they come in, help you put your stuff away, and chat with you for 15 minutes or so afterwards?

Lots of people, and children of people on fixed incomes, will pay extra for that.
