A perennial complaint made by husbands and boyfriends is how their wives and girlfriends expect them to be mind readers. It would be easy to dismiss that aspect of female behavior as simple inconsiderateness. I think there is more to it: the female uses her mate's mind reading propensity as a gauge of their willingness to expend resources on them. Computation indeed is a scarce resource.
In a world with diminished privacy it becomes increasingly difficult for humans in such a world to express their true preferences. If by expressing your preferences you could face sanction (harsh consequences) then you may for rational reasons be compelled to express only the preferences in public which you think are aligned with the community. This is a big problem because happiness requires honest expression of preferences.
Take a match making algorithm for example? If it's a dating app then you have a better chance of finding a good match which makes you happy if you are 100% honest to the algorithm. The problem is when human beings can see your preferences and judge you based on that. For example if you are more attracted to blonde European women then another demographic of humans could see that preference and label you racist.
My point is, privacy is necessary for human happiness to be preserved. Total transparency is not an option unless we do not value happiness at all. If the actual goal of the match making algorithm is to find the best match then the high quality the information you feed it in terms of your preferences the better match the algorithm can find for you. In order for that to happen, no other human besides yourself should see your preferences so that you can be as honest as possible to the match making algorithm. The algorithm would then crunch the encrypted preferences to return results relevant to your search.
This is something possible to write as a smart contract (secret contract). In fact, it proves the value of privacy. Computational kindness takes it much further than a mere match making algorithm for dating. The ability to feed our preferences in privacy to any algorithm can reap massive dividends, whether it's an increased ability to be kind, or abilities we haven't considered yet.
In the context of a relationship, I find it inconsiderate to hide your preferences from your partner and then act indignant when your partner demonstrates his ignorance of them. Otherwise, what you wrote is both interesting and true.
