The scary thing is eye tracking data which could be used to figure out effective decision strategies and could be used to place more compelling ads. When this information along with facebook( used for oculus login), instagram and data they get from google, I would be spammed with all kinds of things.
I am hoping for nice privacy based VR headset but looks like most companies grade eye tracking data.
There are also concerns about control, in Texas there were people who signed something that allowed the companies to remotely control their ac, apparently at night time it was turned up to 82, I am worried about what other companies could do like smart washer ( how about allowed to wash cloths only after 10 pm ) or not allowed to use some setting like extra wash etc.
What would happen if your account gets locked and you cannot access your smart stove to cook a meal. All those people who posted that their oculus was locked out because their FB account go locked out. In my opinion most of these smart appliances are more of a hassle than worth it.
