I read the article as arguing the low hanging fruit are picked, and that performance can't quite make another leap. Can't bump up clock speed because it'll use more power or because the CPU design won't support it.
There isn't evidence that Apple's team has run out of architectural improvements however, so I do think performance gains are still out there. Plus there's always the possibility of going to smaller semiconductor processes.
