Safety, convenience, infrastructure, everything around you isn't solely designed to price gouge you and exploit you, and all of that was just a minor benefit. The biggest thing I felt was an immense existential dread lifting from me. It's like the world millennials were promised when we were young actually exists - working on meaningful things with mental space to breath.
There's too much that can possibly be said of this, but up until now I genuinely thought there was only one way left and we were all doomed to fail, trying to pound sand into intractable problems. I somehow have hope in my life again.
