When you said you are not “getting” AI and technology do you mean not understanding it?
It depends what experience you shared. Could it have identified you as vulnerable to scams or some other disclosure about your financial business?
I am not asking you to say what it was on a public forum only to think about what it was and whether he might have a point.
If having thought about it, you decide he might have then I agree it's not worth arguing about, just be more discreet in the future.
For context my neighbour is 87 plus. She said they were discussing in her coffee morning about AI, asked if I got it as in understood it. I said no and didn’t really wish to, we went on to talk about there being so much identifying information on us out there and I commented about how I felt when someone close to me was a victim of identity theft and fraud and how guarded we are as a result. No identifying information, just that. Probably best to ignore as you say and be more aware of my new listening device 🤣
