Maybe so, but please don't post unsubstantive comments to Hacker News.

Just the title itself shows author has no idea what the hell he is talking about TCP/IP != TCP

TCP/IP refers to the entire stack that Internet is build on, the UDP is actually part of TCP/IP (it was added later for use cases where low latency was important, like telephony). He probably meant just TCP, but that's still "no".

TCP/IP metonymically refers to IP.

My guess is that just saying "IP" is too short.

(And ambiguous - tee hee)

Also Betteridge's law of headlines.

Betteridge's law of headlines strikes again

Should it though?

Quite probably!

I see two main ways to look at this question: will QUIC replace TCP as a go to protocol for developing atop of? The other interpretation is, will QUIC replace all TCP ever written? No, indeed, likely not.
