Honestly, this criteria has always been used and abused by most of the developers. When they're making a new project, what they always tell to their proposals is that it will solve scalable issues and problems. And on top of that, they're making it look like the old ones are outdated which somehow true for some but even with that, we can still see that they're on best shape and usable. That's why if we're looking at Bitcoin, many of those new projects have told that they're solving block issues that Bitcoin can't and at the same time, they keep on always throwing the same description like it's got an outdated blockchain/tech. But look where it is, still the top of them all.
