>>2Nope, still far off.
As far as I'm aware, experiments on memories that involve permanently altering the brain have only been performed in animals, with presumably less complex brain structures.
The way memory is formed and stored is still pretty much a black box. The claims that research are basing on, that RNA is involved in storing memories are dubious, because:
1.) The subjects are mice. They can't exactly talk, so measurements have to be done indirectly. It's entirely possible that those traumatic memories were not erased, but simply clouded or suppressed.
2.) The researchers made no distinction between implicit memory and explicit memory (or to be more precise, between episodic memory and other types of memories). This is important because humans' fear response is based not only on memories, but also bodily functions, as dictated by the amygdala. To say 'erase' is way too far-fetched.
3.) RNA manipulation involves a virus injection directly into the brain. Good luck convincing the ethics committee. And finding participants.
4.) They used to say the same thing about shock therapies. Any improvement?
