Actually, don't ask her, you'll never get her to shut up...
As far as brain-computer interfaces (BCI) to deal with pathological conditions such as brain damage, paralysis, etc., I see a big future for BCI's. My comment is that they will not be used to any successful extent to enhance the
native cognitive capacities of otherwise healthy human brains. Perhaps I should have been more clear on this point in my earlier post.
