You’re aware Siri usage in public may be as low as 3% of iPhone users, yes?

I completely agree that “Siri on your head” will be developed. I just have no idea who would use it, or what it would be used for. (Other than, cynically, keeping engineers employed.) Which is the very opposite of, “You’ve got to start with the customer experience and work backwards to the technology.” Tell me what the experience is that Siri on your head provides that other technologies don’t, especially to generations who favor text over voice in the first place. (UPDATED TO ADD: OK, driving. But that’s a race between how long you get to drive the car, and when the car gets to drives itself. Hm. Which may be why Apple was interested in self-driving cars in the first place, and not just to compete with Google.)

Yes, yes, there are all kinds of movie plot scenarios. Heck, I even remember Niven & Pournelle’s Oath of Fealty, which cuts out the middleman and goes for direct implants.

Maybe I’m being a bit Ken Olsen-ish (“There is no reason for any individual to have a computer in his home.”), but I really don’t see a problem or task that voice UIs solve. If anything, they sacrifice speed, even if they have greater bandwidth and nuance.

(It might be urban legend, but I’ve heard phone tree software has to be programmed to recognize “ma’am,” especially if it’s in a woman’s voice. Because Southern men, a surprising amount of the time, will go, “Yes, ma’am,” and “No, ma’am.”)
