I didn't have a great experience. Perhaps load issues, or the HN hug of death?
I found that the AI kept cutting me off, and not leaving time in the conversation to respond. It would cut off utternances before the end and then answer the questions it had asked to me as if it had asked them. I think it could have gone on talking indefinitely.
Perhaps its audio was feeding back, but macs are pretty good with that. I'll try it with headphones next time.
they're trying to demo low-latency so they more-or-less have to be aggressive with cutting you off. that said, i think they're using filler to buy themselves a second or 2 - try a yes-or-no question
