I been reading less but I keep up with #NealStephenson for hard sci fi. I like his recent near future stuff like:

Fall; or, #DodgeInHell

I'd say it has heart. Neal can be a bit dry but great on the #HardSciFi angle and world building.

Who's doing work like this to create AIs that understand the nature of reality? #AI #dodgeinHell
