"I mean, essentially it's a command line interface with a wonky input method, no?"
This is precisely the feedback we got from salespeople, when we were working on a Natural Language Programming interface for Salesforce. Initially, I got angry and denied the comparison. But after several people made the same comparison, I came to appreciate how true it was. Unless NLP is perfect, it is really just a Command Line Interface with an awkward input device. I talk about this a little towards the end of this story:

The privacy issue is easily solvable IMO. Google already requires a physical mute button on their devices to disable the mics in hardware not just software. It will require either user trust (admittedly in short supply with tech companies lately) or some government regulations but there is no reason even today for devices to have to "record" your conversations in order to process. As long as you require a "wakeword" to tell the device to start listening to your next commands the device doesn't need to record all audio all the time.

Alexa could not get these, which made the skill nearly useless.
It is much easier to simply use a keyboard.
And please consider the failed promises we've heard over the last 3 years. Remember "Invoxia will enable Alexa to tell which person is talking":

So, it's interesting. I resisted the iphone-style smartphone for a long time (I loved my nokia communicators) - I mean, I was super into wearable computers; I owned an Xybernaut at one time; I had the palm v with the cdpd modem... but I resisted the winning form factor for so long.
And... yeah, it was a mistake. Not really a huge one, 'cause the things are designed to be easy to learn over being easy to use (there's usually an either/or there. the easiest to learn process is rarely the most efficient process) but still, a cost; to this day, I'm not all that great at typing long messages on a phone keyboard, like young people seem to be. For that matter, I didn't buy a car GPS until far after they were common, and I am unusually bad at reading maps for a man who started driving before consumer GPS was common, so I would have saved many hours and more than one job interview if I had that technology sooner.
I kind of feel the same way about voice control. I mean, essentially it's a command line interface with a wonky input method, no? and it's a command line interface designed for regular people, not people who are familiar with the command line tradition. I don't think it's super useful now, and I kinda think it will be a fad, like the '80s talking cars.
But, I could be totally wrong. What am I missing out on by resisting the voice controlled garbage?
I mean, if someone does come up with a google maps level 'killer app' that makes you way more effective if you use the voice control, I'll be behind the curve.
