Discussion on the advantages of TCP vs UDP (and vice versa) has a history which is almost as long as the eternal Linux-vs-Windows debate. As I have long been a supporter of the point of view that both UDP and TCP have their own niches (see, for example, [NoBugs15]), here are my two cents on this subject.
Note for those who already know the basics of IP and TCP: please skip to the 'Closing the Gap: Improving TCP Interactivity' section, as you still may be able to find a thing or two of interest.
It's a primer, or a refresher, or a skip. We have all kinds here. Enjoy, or don't.

FTFA:
There's no way to tell the routers in between to drop the already-sent packets because the routers forget each packet as soon as it is sent to the next router. You don't even have the guarantee that all your packets go the same way; how would a router on route 1 know that a cancellation message was delivered using route 2?
The Tao of math: The numbers you can count are not the real numbers.

Don't you get it? "you're hindering the herd"
These "progressive" kids are just chasing the wrong kind of efficiency. Let them make their own internet and let's continue to use ours, unless they start to impose their shit on us like that Poettering dude.
