That’s a nice report.
It’s kind of refreshing to see a realistic review of the various challenges and open questions (as opposed to things like the IBM project claiming they simulated a cat brain when they really didn’t).
What I like about it is that while it’s a huge challenge - Apollo level relative difficulty - it feels very much like something that could be done. There’s no unobtanium required, just a very large effort requiring a huge number of people and a very large quantity of custom computer chips.
