I guess he missed http3, which now makes up 35% of web traffic.

So IETF is the "big, top-down standardisation body" producing "bloated, inefficient and largely unused standards" here?

Wouldn't be the first time someone characterized it as such.

> The internet is an example of the implementation of a top-down approach when a scientist submits a paper for an RFC and iterates on it until it's de-facto protocol of the internet.

Yeah, he must be talking about the IETF. Very consensus-driven, most participants funded by vendors, difficult to iterate after RFC approval.

> While their nimbler competition is being adopted, iterated, and expanded. In the internet protocol use cases, OSI Model is now essentially just a theory taught in networking training, certification, and classes. In the real world, the internet is TCP/IP, and it's TCP IP that runs on computers, phones, and other devices.

Now I'm confused. TCP/IP are literally defined by IETF RFCs.

Technically the Internet runs on "the Internet Protocol Suite" but people just say "TCP/IP" for short. That doesn't mean to exclude UDP, SCTP, or whatever.

http3 operates on a different OSI layer
