Of course it's not the only problem for these watches. Virtually all smart watches lack a fundamental reason for being, sucking at the basics whatever else functionality they claim to implement.
In every day use in a phone however it's a waste of time and probably just taxes the phone far more than necessary for minimal difference to the end user experience.
Otherwise not so much. It just means the DPI goes into stupid territory and the phone OS ends up having to upscale apps to stop them looking like postage stamps.
It is a good thing that that doesn't actually happen and you are just spouting FUD isn't it?
It's not FUD, it's a realistic appreciation of the intractable problems that self drive cars are faced with and hardly likely to solve in an acceptable way in all circumstances. If you think that's FUD I suggest you look at the history of AI, speech recognition, handwriting recognition, robotics etc. and all the false promises made for those technologies and how far we have to go even today.
