This all begs the question: Since AI will likely be embedded into nearly all tech by the next decade, including brainwave tech, will humans even want to use brain implants in the future? I think most humans without any urgent medical need will likely say "no" because they don't want a super intelligent AI knowing their every thought—or it possibly having the ability to hack and control their minds. ...

Naturally, given the possible long-term dangers of super intelligent AI, it would make most sense to limit the development of AI until we have a chance to use brainwave technology to more safely merge with it—hopefully as something like equals, where we can preserve the best of our humanity in the gradual process of becoming transhuman. However, geopolitical issues like China or Russia developing super intelligent AI before democratic nations prohibits the AI arms race from ending. So for now, companies and militaries are moving ahead quickly with developing AI.

This leaves the brainwave industry in a pickle, because AI will also come to dominate that industry, as it likely will with practically all tech. But this doesn't mean there's nothing humanity can do to protect itself.
