almost all claims made by popsci outlets are extremely overambitious.
for example neuralink. neuralink is basically just a further implementation of a technology that has existed for more than 20 years that relies on brain activity and eye coordination but elon musk and the redditors wanking his shriveled cock instantly started talking symbiosis which they heard about from rick and morty or any other scifi shit. in reality human-machine symbiosis is something so far from our current knowledge and capabilities that it's almost impossible.
the problem is that human brains don't act in a logical or binary fashion meaning that we might potentially need to record the profile of every single possible idea, although some progress is being made with visual and motor activities in brains.
