My biggest issue is there are some people I really want to follow who do youtube unfortunately. Other than that, I could see moving off the grid completely more or less.
I do toy with leaving Youtube though and just taking the hit, would be nice to not participate in ANYTHING the big tech companies produce.
I was in Facebook for about three hours several years ago and hated it, haven't been back. Haven't watched any mainstream media in several years either. Still use Google to look up obscure things, though mostly that seems to end up with just going to Wikipedia. I watch stuff on YouTube occasionally, though I'm not "subscribed" to anything. I do not have a so-called smartphone; I have an old style flip phone that does not do texting. I do have a 3D printer which I'm hoping to upgrade to a 4D printer at some point and print out a hypercube and then just disappear into it entirely.
