Yeah, it definitely worth a revisit after so long! Especially after listening to the attached youtube video which is IMO very well done.

You know what, I never thought before that the worlds they go to could be more or less stateless. Maybe you could assume that the hypergates are run by governments but there's nothing to say that they are not run by totally independent parties working for mutual benefit. The cash system could easily be a cryptocurrency.

Lol yeah the re-watch actually got me into thinking some of the stuff that I wouldn't have thought about when I was younger :)
