It really doesn't sound that crazy. Given how quickly technology is advancing, it sounds like a perfectly plausible possibility. My main concern with this type of technology is how it will be implemented into our bodies and how smooth the synchronization process will be when it integrates with the CNS. Of course there are ethical concerns, as well. For instance, if a corporation like Microsoft, Amazon, Meta, or Apple create a product for such a purpose, can we trust them to not abuse it and it's users? I think not. Just my opinion, though.
