Why?
You know if they do, you will most likely be able to disable them, right?
And you know you’ll still be paying for them, right?
You mean just like we're paying for video features?
Ther would be an early adpoter tax. Once it's present in every camera there won't be any cost associated to it. And even then, it's not even 100% there would be one, as computational features are the next logical step when you have more powerful processors... If camera processors get powerful enough, not only will there be no cost, but every camera would have those, will not even be a matter of "paying more to get access to that feature".
