The networks, OSes, ... weren't ready to accept a new protocol at such a low level, so it never worked reliably over random public connections and stayed in a niche for internal use cases. Things like QUIC, WebRTC, MP-TCP, ... rebuild aspects of it over TCP or UDP to get around this problem.

I guess that makes sense. I remember doing a research project in school and it seemed then like it would be the future. IoT and mobile phones would definitely benefit from a connectionless protocol like that.

That is the very reason I use `mosh` to connect to my servers. My laptop isn't always on the same internet connection and I'd prefer not to have to reconnect all the time.
