On a less trivial level, consider what peer pressure looks like in the society without the privacy of your own thoughts. What if that society, for example, turns out to be religious (like the current societies)? Are you ready to be part of a shunned minority?
I think about this a lot, but my expectations are radically different from yours. Peer pressure depends critically on maintaining the illusion of a uniform mainstream position. The awareness of just how much variance there actually is in real populations tends to destroy its effectiveness.
I expect a telepathic society to experience much less in the way of peer pressure than my current society, where 90% of the population can claim to believe X, even though they really don't, because they see that 90% of their neighbors are claiming X and they don't want to be singled out for defection.
But sure, if I'm wrong and the telepathic society turns out to be the kind of narrow-minded thoughtpolice scenario you have in mind, I will be surprised and regret my choice.
I asked this question on IRC before and got some surprising answers.
Suppose, for the sake of argument, you get cryo-preserved and eventually wake up as an upload. Maybe meat->sim transfer ends up being much easier than sim->meat or meat->meat, or something. Further suppose that you are not particularly averse to a digital-only existence, at least not enough to specifically prohibit reviving you if this is the only option. Yet further suppose that sim-you is identical to meat-you for all purposes that meat-you cared about (including all your hidden desires and character faults). Let's also preemptively assume that any other attempts to fight this hypothetical have been satisfactorily resolved, just to get this out of the way.
Now, in the "real world", or at least in the simulation level we are at, there is no evidence that telepathy of any kind exists or is even possible. However, in the sim-world there is no technological reason it cannot be implemented in some way, for just thoughts, or just feelings, or both. There is a lot to be said for having this kind of connection between people (or sims). It gets rid of or marginalizes deception, status games, mis-communication-based biases and fallacies. On the other hand, your privacy disappears completely and so do any advantages over others the meat-you might want to retain in the digital world. And what you perceive as your faults are out there for everyone to see and feel.
As a new upload, you are informed that many "people" decided to get integrated into the telepathic society and appear to be happy about it, with few, if any, defections. There is also the group of those who opted out, and it looks basically like your "normal" mundane human society. There is only a limited and strictly monitored interaction between the two worlds to prevent exploitation/manipulation.
Would you choose to get fully integrated or stay as human-like as possible? Feel free to suggest any other alternative (suicide, start a partially integrated society, etc.).
P.S. This topic has been rather extensively covered in science fiction, but I could not find a quality online discussion anywhere.
