I grew up listening to my Grandpa talk about the merits of the .257 Roberts.
Sure, he owned a .30-06 as well, but he loved that little Japanese Arisaka that he re-barreled and chambered in .257 Bob, with a sporterized stock that was common for gunsmiths to do in the post-World War II era in the US.
It would be interesting to see the statistics on production numbers for each of the new cartridges that have been introduced over the years.
I can tell you that 6.5 Grendel has a lot better numbers than most of the ones on that list, and is in the top 3 of all those center-fired cartridges, maybe even 1st. Since .300 AAC just barely started having steel case made for it, there's a good chance 6.5 Grendel ammo production from all the major manufacturers has eclipsed .300 Blackout, which has been marketed heavily by Remington/Freedom Group while having some of the worst ballistics of all the new centerfire rifle cartridges available for the AR15, if not the worst when looking at supersonic loads. This shouldn't surprise anyone since the cartridge dimensions were primarily intended for subsonic use, with a supersonic option shooting lighter bullets.
If I was going to pick 3 of those 2000-2020 cartridges that will continue to drive on in popularity, they would be:
6.5 Grendel
6.5 Creedmoor
.300 Blackout
Since the 6.5 Creedmoor is not able to fit in the AR15 frame, I think it's a testament to how well Hornady has marketed and supported the Creedmoor, along with its obvious real-world performance that sells itself in-place of where most people used to get .243 Winchester and .308 Winchester.
