An excellent point. I've been asked quite often by my history students if I'd be willing to go back to 1978 if I got a billion dollars for it. And the answer is not just no, but hell no. In theory I could give up the internet, Amazon, Spotify, and all the rest, but what I couldn't give up is access to all the micro-communities that use the net to develop their interests, and I couldn't give up the access to the world's knowledge, right here, at the push of a button. That's wealth, as you say. Wealth unimaginable.
