Mind reading, a possibility?

I was never concerned this much about privacy issues before I read this. To sustain a society that's built on "diplomacy", "political correctness", and a delicate unsaid contract, it's extremely important to have privacy of thoughts, a dark cupboard to put our skeletons in. On the other hand, in a hypothetical world where all dark corners are illuminated, there would be no room for hypocrisy, perhaps paving the way for society as a super organism. That'll kill the notion of a free-thinking individual. As an individual, I feel like the protagonist of the Orwellian 1984. But does this all matter once the transformation to a superorganism is complete?
