Appreciate the push-back. I think the speed/integration of exchange is actually fundamental. Like before the printing press there were manuscripts, and before the written word there was oral tradition…but advances in what could be called simply an upgrade in speed, repeatability, etc. have consistently had incredible effects on consciousness, intelligence, human organization, etc.
I think it’s highly unlikely that connected brain interfaces would be an exception to the rule. If you can’t differentiate between “your” thoughts or emotions and those “put there” by others, for example, the entire self/other construct seems as though it would inevitably crumble.
