In a future where machines make payments to other machines, it would need to be in a currency that's unstoppable and verifiable, and occurring over a 'identity' platform that is unstoppable and verifiable, like Nostr.

Orange and Purple pills go together. The future will be freedom oriented, no middlemen, no censorship, no black-box hidden code, or humans meddling in the operation of the network. Nostr is the only thing capable of being the neutral backbone of a network for unstoppable payments and identity/accounts. Can't have political bias/Parties/deep state involved and actively intervening if our economy will be including machine to machine payments.
