And I only read the Monadology. But apparently its the only thing by Leibniz one really has to read, unless they intend to become a scholar of his work.

Does anyone have a good recommendation for an introductory book on these concepts?

I read a bit of The Fabric of Reality but had trouble progressing too far with that one. The author talks about the quantum slit experiment, somehow arrives at the explanation of parallel universes, and then claims anyone who disagrees with this conclusion must have faulty logic. A huge chunk of reasoning behind parallel universes seems to be skipped and I have trouble taking it seriously every time it is brought up.

The hope when I was on the standard body was that norms would shift as technology enabled it to be shifted. That’s also the reason the ID can contain multiple records that attest various proofs while preserving privacy (eg a store age check for restricted items or bar age check wouldn’t get anything other than your photo and a statement that you’re over a certain age without revealing your name, birthday, etc)
