Ha. "Small price to pay." I stick with Apple because I am, in no way, interested in paying that "small price." If you don't want to pay that small price, you currently have a choice. If Apple gives up on that my options are basically having nothing to do with AI in that regard.
If you want what Google does, get Google's products. Problem solved.
Siri tends to do exactly what I want. The reality is that I haven't found any AI solution that's faster in most cases than I am making a query in the program that I want. I use AI for simple stuff I so hands free: reminders, hands-free dialing, and I imagine it would be relatively handy when I start using smart devices in my home.
Do I really need a speaker listening all the time so I can place an order on Amazon? I'm in no way saying the feature isn't cool or that no one should use it. But, for me, it's not that useful, even at the "small price" I have to pay on those services.
Apple's HomeKit forced encryption is a big deal to me. Again, if lowered security and privacy standards are a "small price" then you have a myriad of options in the market. I find Apple's focus here to be very appealing, even at the loss of functionality. (And, as I said, as a voice assistant Siri does just fine for my limited use cases.)
