I can also walk over to my kitchen, stepping around the dogs and cats, and pour a glass of milk in about 90 seconds too, but a robot that can reliably do that would be pretty damn revolutionary.
Don't underestimate the insane quantity of wetware computation going on during a short conversation.
It is entirely unclear to me that a bot that might make simple reservations at small group of establishments that include only restaurants and hair salons is in any way revolutionary. Even if it worked 100% of the time, who is making daily hair and restaurant reservations that would benefit from the extra 90 seconds? It's silly the amount of hype this is eliciting. You have a very strange definition of "revolutionary".
The wealthy have had assistants since practically time immemorial, and no one bats an eye at their "90 seconds". The promise of this tool is a democratization of both the convenience and the normalcy.
If it is an extensible technology that requires relatively minor tweaks to expand the domain of applicability, then it is revolutionary thougj the effect won't be fully felt until it has been more broadly applied.
If it is narrowly tailored such that the next two domains will cost nearly as much time and money to build out as restaurants and hair salons, then, sure, it's minimally useful.
Google's been promoting it as the first, and that seems in character with what Google does.
Doesn't matter if you're only interested in it as a consumer. But then why would you be on HN?
Your entire comment would apply to introduction of the first transistors, which were worse than vacuum tubes in almost everything except size - and nobody at the time particularly cared for their size.
The harder part is voice to text (not rocket science and that can be done pretty reliably) and natural sounding text to speech.
For the $9.99 a month that Dropbox costs for a terabyte, you can get Office 365 that includes One Drive for 1Tb each for up to 5 users.
You might think this isnt new "AI" technology, but as others have showed this is the first time we've seen an "AI" tech convincing masses that it is real human using voice.
