Brain implants are and were dumb on their face.
It turns out we have several excellent brain interfaces available and honed over millions of years of evolution - our eyes, ears, hands, voice, and a bunch of more subtle ones like touch and balance. They are intuitive, built-in, and free. And none of them are permanently invasive, which saves all sorts of biology issues.
The only real use-case for any sort of implant is where you have no alternative - the pacemaker comes to mind. The rest are someone trying to sell you something you don't need or want.
