Completely disagree.
First- What is the obsession with Siri? Siri is just one of many voice-recognition engines. Albiet a decent one, but others have caught up and in some use-cases surpassed Siri.
Second- I find it very hard to believe people will want to talk to their house locks, their appliances, and everything they own. Most of us do not like talking to inanimate objects. It's awkward, especially in public.
No matter how good or natural speech recognition gets, some conversation will always remain awkward: "Siri, how do I get to planned parenthood?" "Siri, what's my bank account balance?" "Siri, download the latest episode of *insert terrible show you enjoy*" "Siri, it hurts when I pee" "Google, open a new tab in incognito mode" "Add my gyno appointment, next week Wednesday at 3pm" "Remind me to call out sick on Thursday so I can go to Six Flags"
Third- Although voice recognition has gotten pretty dam good, it is not even close to perfect. Some day it most likely will be, but I doubt it will be in my lifetime (and I'm pretty young). It's decent at recognizing general speech today; but compared to what we humans consider natural speech, it's still terrible. Humans can sit in a crowded room with several conversations going on at the same, and they can easily identify which voice belongs to which person, they can (if they concentrate) listen to several people all talking over each other at the same time and understand what each of them is saying. There are tests that show we can listen to and comprehend on a basic level three conversations happening at the same time (meaning, we can summarize each one after they are over). Until voice-recognition can do all of that and more, it will feel too unnatural talking to a machine. Siri right now barely knows when to question mark at the end of an inquisitive statement.
Fourth- Until the above is met, we tend to rely on using voice recognition when typing isn't convenient. Everyone has a plethora of reasons why typing isn't convenient - driving, hands are full, lazy, can't see, etc. However, I know of very few instances where people said they actually prefer to use voice recognition to typing when none of the above reasons are a factor.
I'm not saying the way we interact with technology won't ever change. However, I think we will continue to use non-verbal means of communicating with technology. Be it eye-ball tracking cameras, touch-screen surfaces, gesture-recognizing algorithms, or telekinetic control (
); I am certain we won't be talking to the dishwasher.
TL;DR - Dream on, not gonna happen.
