The speed aspect is impressive, but I'm really disappointed about the "natural" conversation feature.
Like at first, I was super impressed with the presentation, but on the app, there's one crucial difference: you need to tap to interrupt.
Watching the presentation, I was thinking maybe there was a continuous input feed, and the AI was reacting to that in real time - so for example, if I said "Ahh, I see", the AI would hear that, but continue talking.
However, it seems like the input is still broken up into request/response the same as before, and this is actually just a new front-end (with some improvements in the response).
So overall, this is kinda neat, but sadly it's not at all what they seem to by hyping it up as, as far as natural conversation goes.
