The bad news? Steve fucking Jobs still has a devoted postmortem following for no fucking reason except that people felt that cool with ipods and iphones while he was being an abusive asshole to everyone around him and stealing credit from people that actually made things. 
Nobody will remember Elon Musk ten years after his death, and that will be a good thing. The engineers who actually did any of the good inventions will come out.
His brainwormism is equally as harmful as every impact he's had on the material world.
I truly hope so.
