Even the fun things “on the internet” are mostly still possible, it’s just the bulk of things we do now are not fun and main companies aren’t quirky risk takers but the oil/train/steel barons of our day.

In the past few years I’ve done serveral of the things on your list in earnest and they are all easier to do today (specifically technical things) than they were 25 years ago (except maybe writing with a pen).

Edit to add: if I have to join another messaging platform for a single, specific group I’m going to move to the woods and require written correspondence. It’s automated phone service level of frustration.
