Can advances in neuroscience help attain enlightenment? Will it make Buddhist traditions obsolete? Correct me if I'm wrong, but I understand that Buddhists view enlightenment as a state of mind. As neuroscience progresses, we have more and more control over human brain, so inducing particular states of mind seems to be just a matter of time. Does it mean that at some point in the future, assuming that the science continues to progress, we will be able to cause enlightenment by neurosurgical means? Or is there something in enlightenment that would make it impossible?

If we reach that stage, will it make all the Buddhist traditions and scriptures obsolete? After all, enlightened people can see things clearly for themselves, so there would be no point in relying on such very old sources with unknown reliability, which were heavily influenced by their cultural contexts.
I think that if someone has a brain disease that is interfering with their practice neuroscience may be able to fix their disease allowing them to practice, but apart from that I don't see much help it can do.

Enlightenment isn't a peaceful state of mind. It is the product of gaining very deep insight into the very nature of reality itself, and I can't see how neuroscience can implant even ordinary knowledge in a person, so how much less possible would it be to artificially create in a person the profound non-conceptual direct perception necessary to reach Nirvana.
