One speaker is a professor from UCSF who studied the brain's processing of motor signals. He explicitly credited Musk for having the right vision and the long term planning, and that's why he left his position after 16 years to come work with Neuralink.

No one credits Musk for solving bugs with the software on his products, or creating these brain-computer interfaces. But he can assemble the team to do, and motivate them to keep moving and progressing pretty aggressive schedules. And he frequently gives credit to his team (and doesn't sit there patting himself on the back).
