And yet, until Tesla came about we didn't have that many electric cars running around, nor did we have many companies investing heavily to change the status quo of gas cars. The same goes to reusable rockets. As many other people said in this thread, Musk is a PR nightmare and is a very peculiar public person when it comes to his tweets and such, but I wouldn't put it past him to actually find the talent and bankroll this until they achieve their objective.
There's no doubt that Musk has a knack for high risk entrepreneurship and he definitely very well how to repackage and promote things, but Neuralink wants to invent devices that come straight out of the science fiction realm.
Not only do we not have the AI required for natural language processing of the sort Elon is after, we also don't really have the neuroscience that explains how information is stored in the brain or let alone how we "write" to it. That's a different beast.
