elon musk, basically a business man with computer knowledge, should not have his name mentioned in the same sentence as nikola tesla, let alone be considered an inventor. he reverse engineered russian icbm rockets for blasting shit into space. he did not invent blasting shit into space. kissing musk's ass is like kissing visa/mastercard's ass. also, until we take care of the problems here on earth, blasting shit into space is a silly distraction to many, and an untenable expense to many more. if you want to compare elon musk to a historical figure, try henry or robert krups, but not edison. i want to give credit where credit is due.
