I came looking for a discussion of this on the back of just watching Bilawal Sidhu's recent “The Craziest Mapping Breakthrough Since Google Maps” https://www.youtube.com/watch?v=F-S-x0b9TrE

And tbh I didn't expect much of or any discussion because my feeling is that Hacker News is a forum which has long since only masqueraded as a geek/tech bulletin board and discussion forum. And this here absence reinforces that feeling.
