Some of America’s best thinkers (including my mom) have raved about Yuval Noah Harari’s book Sapiens: A Brief History of Humankind.

But our fate at the hand of clever clogs robots may in fact be worse — to summon a class of eternally useless human beings.” (Finally, a role for which we’re over-qualified.)
