I am fully opposed to subscription requirements in hardware I have bought. Anything that the hardware can do, the hardware should be doing without the customer paying extra for it. Case in point would be Mercedes making rear axle steering (for reduced turning circle) a subscription service. So they installed the hardware but they will not let you use it unless you pay them monthly. Or BMW making heated seats a subscription service. This is a basic function of a car seat and in one of the most expensive brands you would expect not having to pay extra for it. Cloud services on the other hand, that I can accept, as long as it's not something that would have previously been included in the hardware (such as remotely locking/unlocking and checking alarm status, which I currently do using my fob).
As far as cameras, I suppose I don't see the need for my camera to be linked directly to the AI cloud. I could see it being connected to a computer for simply transferring images and I hope that will not be a subscription service because it seems to be rather basic these days. However, what happens after that is where I can see the use of AI. Pictures need to be sorted, enhanced, cropped and so on. I might do that manually but I can see AI being very useful in doing this and picking out the best when you have hundreds of pictures out of camera. All those things I would normally be doing myself in GIMP could be done by AI, just faster. better and at a lower cost. Photoshop could actually be made obsolete as far as working professionals are concerned.
