Sorry, I can see why you might take that the wrong way. In my defense, I consciously wrote "generally speaking" in the hopes you wouldn't think I was referring to you in particular. I wasn't trying to accuse you of anything.
I strive to not criticize people indirectly: my style is usually closer to say New York than San Francisco. If I disagree with something in particular, I try to make that clear without beating around the bush.
I specifically said: "But anybody with enough experience in tech can count a lot more instances of 'the world is about to change' than 'the world really changed'. I pretty clearly understand that sometimes the world does change.
Funnily, I find it suspect when people accuse me of failing to do things I did in the very post they're responding to. So I think this is a fine time for us both to find better ways to spend our time.
