> Perhaps the most irresponsible illustration of this is Elon Musk who has made his substance use so overt I think it wrongly and perhaps dangerously couples using to entrepreneurial success.

oh come off it, what substance abuse? he toked on a blunt on JRE once (clearly barely inhaled and even then, so what) and has a few bourbons with his brother on yearly retreats? please provide more info about this, because i've never, ever taken musk to be that sort of guy.
