Co-author of the book here. Thanks for the comment. I agree, it does seem surprising to miss NAT. I opened an issue (which we will address at some point): https://github.com/SystemsApproach/book/issues/75

And people say The Register doesn't do funny headlines any more.

Saving it for another post. It is actually just as controversial as there was a lot of work to improve convergence times in standard IP routing at the same time.

Part of what we're arguing in this article is that there is no good answer today because of the assumption that TCP was good enough. Homa is challenging that assumption (as many others have tried before). My view is that if you want something better than TCP for RPC today, QUIC is the best thing available, as discussed here: https://systemsapproach.substack.com/p/quic-is-not-a-tcp-rep...

What you run over that for your RPC is a matter of taste - gRPC is certainly popular, and can be run over QUIC.

How many times has Intel tried and failed to enter the networking business? I’m keen to hear more about this story but it sure seems like they’ve decided they can do much aside from CPUs at this point.

Label distribution in BGP covered a lot of the most impactful use cases, RSVP_TE covered the next tier.

Author of the post here. Good comments. I was being deliberately provocative in the title to make a point. As I note in the article, it may or may not turn out that QUIC replaces TCP; the main point is that we didn't need a "TCP replacement" as much as we needed something new to meet the requirements of RPC (and HTTP in particular) and QUIC is doing that nicely. It may turn out that is all we need and TCP disappears, but as you say, there are reasons to doubt that including the extent to which TCP is baked in to existing systems.
