I do know, for a fact, that having a more capable and powerful voice assistant than, the already fairly capable, Siri, will be a game-changer (for me at a bare minimum, but I’m not that special so I think it’s safe to extrapolate that to more people).

That’s a fact.

I also know that voice-interfaces to date have been incredibly stiff and there is ample room for improvement. I know, for a fact, that having AI enable better voice interfaces will make computing better and more accessible. I have a hard time understanding how those are hype-driven comments and/or opinions.

We do know these things for a fact. Not being able to articulate exactly which breakthroughs will be most important doesn’t make it hype.
