True, I can see Variable insurance premiums based on your likes / friends, it _is_ a scary prospect. I guess a similar problem applies to any form of insurance.

True, I can see Variable insurance premiums based on your likes / friends, it _is_ a scary prospect. I guess a similar problem applies to any form of insurance. I don't know if it's wrong to do that though, if it leads to lower insurance premiums to the rest of the world. Insurance companies already tend to do a real world equivalent of what you talk about, but at a much lower level. For (2) and (3), Agreed again, but what does it matter if you're just a data point to Big Corp A? Do you really expect them to treat you as an individual even if they don't have any of your data?
