Oh my word, it's like you wrote a post especially for me... ;P
First of all, be careful with that thumb of yours. Repeated Stress Injuries are no fun. I've started experiencing a bit of it in my left wrist/hand/arm - it hurts, I tell you!
But that brain is just perfect. If you put it on MakersPlace, I'll buy it for sure. And how about the actual work? For sale? =)
It'll probably come as no surprise that I've often thought about the things you touch upon in this post. And honestly, a collective mind is exactly where I think we're headed as a species, and Elon's Neuralink might just be the pioneering company that starts it all off.
It's going to be fascinating to see how it all plays out - or at least it would be, if we were able to live long enough. Would we lose our individuality completely in the end, or would we be able to maintain a kind of hybrid system where we could plug/unplug ourselves into the "omnimind" at will? And how would that feel? I imagine it would be like going to sleep and having perhaps having an extremely vivid dream of being the omnimind sentience.
Oohh, and you know... Maybe blockchain-like structuring would help in keeping our individuality somehow?
