I suspect most people will land on this where their predilections already lead them. To me, the effort to delay Mathematics education is sufficiently bad that I can dismiss the rest of that school of education without much concern. If they are right, they are right by accident and there's not much to learn there. I know there are others like me out there, and for them a quick reminder of who this person is will probably be sufficient for them to escape reading (what they will believe to be) a low-quality post. Time isn't infinite after all.
If you feel less convinced by this, it's simply that you're not in my audience. But I think it's probably worth sticking a tl;dr on the original. Let me do that.
I usually regret reading Dan Meyer's articles, but this one I really enjoyed. It pointed at a couple of sources that led me down a rabbit hole back when I encountered it.
I don't know whether Dan Meyer is in favour of delaying math education. I do know he favours delivering education in a school setting with in-person human teachers, but the latter doesn't imply the former.
