I think so? They’re all expanding, of course... but none have really changed that much over the past few decades. There’s a ton more VCs than there were a decade ago, but has it really changed as a field? People tweak the formula a bit, but we haven’t seen a shift in the same way YC shifted things. To a lesser extent, pg was one of the first “tech essayists” (now it’s a genre,
http://waitwho.is).
I don’t think pg is saying they’re being ignored, but rather that there’s a sense of “yup we figured it out, let’s just iterate slowly on it”.
(I will say I can think of much better examples, but I don’t blame pg for picking the three examples that sum up his entire career. He picked those three things when nobody else cared.)
