I think this is a useful lesson - because we still call it "the Internet" and yet the protocol has quite evolved over the time. SPDY being pulled in as HTTP/2, QUIC as HTTP/3...
I still remember optimizing websites performance because of the issues with HTTP/1.1 and trying to fit the first response in 1500 Bytes MTU, so we save another roundtrip during the slow start.
It's the tweets like this that make a direct comparison: https://twitter.com/TuurDemeester/status/1087459292821811202
I can just see the shitcoiners replying: "Oh TCP was replaced with QUIC, so BTC will be replaced with my shitcoin"
