The book is about stress and the impact of glucocorticoids on the body. The chemical stress response used in "the wild" by animals is actually the same as the stress response we have when worrying about losing our job, not being able to complete a paper for school, dealing with poverty, etc. It's a partial explanation for why modern humans have so many chronic diseases that are rarely seen in other animals (or even archeological/anthropological evidence of non-industrial societies but he doesn't really go there much in the book)
I also highly recommend Sapolsky's Human Behavior Biology course which he taught for Stanford but published on YouTube:
Do you seriously think Elon works 100 hours a week? What evidence do you have to support this?
Most people do find fulfillment out of work, many even enjoy it, myself included. That doesn't mean that we shouldn't fight to be compensated for what we put in, and doesn't mean we shouldn't practice solidarity with coworkers, many of whom don't have the time to work as much as we do (for example a working mother).
Exactly. A lot of Elon's "working" hours are doing completely unproductive things that he enjoys, like posting childish memes on Twitter or belittling people he has power over.
Because it is based on Git, jj is not a CRDT, it seems to be a better merge algorithm (even though the details on their algorithms are scarce).
When I say "not a CRDT" I'm obviously talking about HEAD not being a CRDT, a Git repo is append-only, so the history of a Git repo actually is a CRDT (but that's not what the comment above meant).
