Ask HN: Are you comfortable with a brain interface?

It seemed that NeuroLink would be getting to the point where they could reliably do it. But since seeing the facts underlying Tesla's "self driving", and the fast/loose nature of that... I no longer have any confidence in their work.

Elon pushes people to get results, but he pushes too hard, in general, to be sustainable in the long run.

Is it invasive? (Will I have electrodes implanted in my skull?)

Is it intuitive? Can I just think and things happen or do I need to deeply concentrate?

Are there harmful side effects? (Using it causes headaches or might induce seizures?)

Can I trust the brain interface creator? (Are they lying about possible risks? Can they "read" my thoughts without my permission?)
