I agree that "still just demos" is an overstate. But I'd say that in 2015 a lot of people predict that in 2020 we'd have driverless Ubers everywhere. And that just didn't happen.

The challenges that are still open in getting driverless vehicles to operate in more chaotic scenarios like India or Latin America seem pretty much in line with what he's talking about: new improvements need exponentially more data.
