21 Lessons for the 21st Century

Great if you've never read Harrari's books, a bit repetitive if you have (although I've also read a few long articles, so I might be over-exposed to his stuff). He still doesn't provide any answers, only problems, but he's also right about most of the stuff.

Some chapters are new and interesting, e.g. last two on meditation (and no. 15?)

Still, if you're reading only one of his books, read Sapiens.
