I think the hallmark of being “old” on the internet is embracing the technologies that actually enhance the use of your time and talent and forego or ignore the ones that do not.
I’m sure my 11 year-old daughter disagrees that TikTok is a waste of time and I respect that. But it doesn’t mean I have to understand it. My parents probably felt the same way about BBSes.
I just have to make sure she’s safe and that’s all. She’ll figure out the rest.
