We are all social animals and one of our core needs is human connection. I guess the question is, is this the right thing to do for our humanity? IMHO the answer is no? Creating a more isolated society has much more dire consequences.

The at what scale question is the tricky part. It’s so different for everyone based on personal habits and values Eg. I’m a social animal so will always need human 2 human energy to survive.
