If you're content playing a long-game and taking a bet that Neuralink is successful as a company, it might be better for a career to spend some time with a well-known company like that and then cashing in with your next role rather than finding a little better pay at an unknown hospital right now and not having any notable career accomplishments for the rest of your career.
