I wouldn't stretch as far as calling Musk a genius - he's someone with a lot of business acumen, and understands how to use social media effectively to get what he wants (much like Trump), and has deep connections to make his ventures successful.
SpaceX, Tesla etc would not be where they are now without all the funding Musk was able to secure and source from governments (grants, tax breaks, investments etc), and then investors - that's probably his biggest contribution.
