Those smart minds have mostly left spacex now, since musk changed political sides and became much less 'cool' for the brightest to work at.
That's why the company is struggling now - few smart minds means little progress.

But due to musks political aura (mostly right leaning), the smart minds from universities(which are mostly left leaning) are no longer joining spacex en-mass.
In turn, that means the companies are merely ticking along, not racing ahead.
