If the company or a hostile government goes after my phone or internet, I can live without it. My brain?
I can choose to live without internet, and it would suck. I can choose to live without electricity, and it would suck. But I can choose it.
I cannot imagine a future where my brain, my actual living brain, is interfaced with anything that I do not have complete and utter control of. And it might suck, I might miss out on entertainment, medical treatments, or whatever, but you have to draw a line somewhere.
There's being a Luddite and then there's being skeptical of something that can really mess you up. I am convinced being absolutely skeptical and refusing to participate with brain interfaces owned/operated by a third party is not being a Luddite.
