> Without a doubt, C has "lost" nothing, because it barely changed

Thanks to UB exploitation, C as implemented has been changing a lot over time. Old C was a decent low-level language. New C is barely usable.

I'm not following. Can you give an example of such changes which make C less-usable? Also, are you referring to changes in the C standard or just the implementations?
