If you could have the ability to hear everything your best friend or romantic partner was thinking, but you couldn't switch it off (or tell them), would you want it?
I have a feeling that the people who answered "yes" didn't really think this through. We, as humans, do not think in full sentences, our thoughts are fragmented, chaotic, confusing, contradictory and overlapping. Have you tried reading Ulysses? Well, imagine having to listen to that 24 hours a day. I would probably last six hours tops before I killed myself (or the person whose incessant thought-jabber I'd be hearing), so the answer is no, not ever.
