The Star Trek vision of voice as an interface is a good vision. The question is how the regulatory framework protects users in this world and keeps it from being the dystopian nightmare that our "for profit corporations get to do whatever they like as long as you agreed in an 'all or nothing' click through" seem to be headed for.

That's not really observable or enforceable by me though. A question I ask myself all the time before I say yes to some kind of "new data tracking" is: "How do I think company_x will behave in 10 years if their profitability is plummeting?" Because I think that paints the worst case for companies that so far have been good actors.
I guess the TLDR is: That's great, but I think that the solution is legal protections for users. Right now all the power is in the hands of the collecting organization.
Voice interfaces today work like keyloggers by design, and we're just trusting them not to abuse all the data they're getting. It'd be a lot better if we didn't have to.
(I'm on board with legal protections too, of course.)
We are far more likely to end up in a cyberpunk nightmare where corporations are richer than entire nations and technology is used to subjugate and control people.
