I don't see it as condescension though. I think it's just a way of speaking.
It's one thing to joke about it a little, but this is just arrogance on display with obvious derision for us children who find that traditional syntax highlighting is beneficial.
I recall reading once that Vim tabs were a crutch for people who "can't remember what they're working on". It's the same kind of arrogance and presumptiveness.
This would be a wonderful idea in any programming language.
But I agree with the other commenter that this speaker is really condescending. Not a person I'd want to work with.
"You've all seen syntax coloring, right? That's something we put in our text editors to make it easier for kindergardeners to do programming"
