I agree that it's an easy to fake demo and at the same time, if they're going to fake it, why make it seem so slow?

As to whether typing speed is a bottleneck for most people, maybe not most people, but definitely some people, and it's a massive bottleneck for me personally.

I think better when I'm talking and since I have started using speech to text, it has increased my writing speed and coding speed by at least an order, maybe two orders of magnitude.

But you are right, the AI filling in gaps can really cause trouble using speech, goodness knows what it's doing using sub-speech.

Honestly I have no idea if it's fake. I wouldn't be surprised if it's both fake and real: the actual video is entirely fake, but a reasonably accurate demonstration of actual capabilities (like a lot of tech demos at live events...)
