The one thing from your description that threw me off was " it’s a more familiar medium, like texting with your family."
I don't text with my family. Or with anyone, really. It is a running joke that the last way you'd want to get in touch with me is by text. My kids text me just to take bets on how many days will go by before I see it. Maybe I'm the exception... but I'd encourage you to re-visit whether that really is how people who are 50+ would prefer to communicate.
