I feel like nowadays that joke has evolved to devs that use JSON vs devs that use binary serialisation (like capnproto or whatever else)…

[xarope]

Not that much of a joke, a lot of companies are using binary protocols for internal services e.g. gRPC, and REST for external. So, best/worst of both worlds (depending on whether you are a glass half full/half empty person)

Why not both? There's a binary serialization format for XML... (https://www.w3.org/TR/exi/)
