> What if instead of connecting just 2 people’s brains together, we connected everyone’s brains like that to the internet? Would that mean that every human being on Earth would feel like they are just one small body part of a single, greater being?

I don't think that joining everyone's brains together would make everyone feel like a small body part of a single, greater being, because our brain architecture really wouldn't support that. You might be able to handle some shared "input" with another person or a small group of people (like these conjoined twins who share a thalamus[0]), but you're going to run into bandwidth issues pretty quickly given that there are only ~1-2 million nerves in each optic nerve[1]--if you're trying to split that 7 billion ways, you're going to have a difficult time getting coherent information through, let alone processing it.

The second major limitation to joining brains together is the speed of light--once we're able to open up communication between brains to allow "communicating via thoughts", we'll be communicating at the speed of our thoughts, which is much faster than physical speech. Connecting your brain with the brain of someone on the other side of the world might be a pretty disappointing experience because they wouldn't be nearly as responsive as someone physically nearby. Uploading brains and running them at higher "clock speeds" than biological hardware permits would make this limitation more significant, because you might subjectively experience a communication time lag that would feel like hours, days, or longer when connected to someone far away. In other words, there would be a limiting radius in physical reality for effective brain-connecting communication that varied depending on the speed of your subjective experience.

Those limitations aside, sign me up! Brain-AI merging and brain-brain communication are going to be the bees knees.
