They are indeed in their infancy. The big risk I see is that by implanting a chip into the brain is a surgical procedure, and with any surgery there can be a chance of infection. Encephalitis is not something I would be willing to risk to have a chip in my head, plus chances of toxicity from the metals in the chip itself...
Hard pass on my part!
You raise valid concerns! Brain-computer interfaces are definitely early stage, and safety is paramount. While the potential benefits are exciting, minimizing risks like infection and toxicity is crucial. Perhaps future advancements can address these concerns.
