Would you be worried about brain implants becoming mainstream?

I’d separate medical use from enhancement. Helping someone regain a lost ability is a very different case from selling optional upgrades to people who are already healthy. The first can have a clear medical purpose. The second raises harder questions about pressure to keep up, who gets access, and whether opting out stays a real choice.

The privacy question seems bigger to me than the dramatic promises. If a device interacts with the brain, people should know exactly what information it records, who can access it, how long it is kept, and whether they can fully stop using it. Until those answers are clear, claims about convenience or enhancement feel premature.

I’d be cautious about treating a video’s description of long-term ambitions as evidence that those abilities exist or are close at hand. A possible future feature, a company’s stated goal, and a working product are three different things. The medical uses and the more speculative ideas should be discussed separately.

For me, consent would have to be ongoing, not just a form someone signs once. People should be able to decline, remove or disable a device where medically feasible, and get care without being pushed toward an upgrade. I wouldn’t rule out an implant for a serious medical need, but I’d need a strong reason and clear safeguards.
