I find voice AI creepy as it's always listening. If you have to press a button to get it to start listening then you're better off typing your query. Plus I scan and read faster than an AI reads responses. I'd pay more for products that dont support it. (similar story for smart TVs).
But of course there is no option for that as they think advertising is more valuable. Worse they have set the initial price as free and so now most people will object to paying despite how useful it is (I've seen some uses of Alexa that are probably not worth a monthly price, can they make money on $5/year for 10 devices?)
