Note that CRDT isn't "a thing". The CRDT paper provides a way to think about and analyze eventually consistent replication mechanisms. So CRDTs weren't "introduced", only the "CRDT way of discussing replication". Every concrete mechanism described in the CRDT paper is very old, widely used for decades beforehand.

This means that everything that implements eventual consistency (including Git) is using "a CRDT".

Drug costs are contentious because they're easily visible and often no covered by insurance. The other costs are obfuscated in complex billing and hidden under principle/agent veils.

E.g. my son has a peanut allergy and so we need to buy EpiPens. They were hundreds of dollars, and the vendor played MBA-nonsense games like requiring two to be purchased at a time. Meanwhile I was able to drive to Canada and buy the exact same thing (and as many or as few as I needed) for tens of dollars.
