Earlier quoted context omitted.
Taleb is literally mostly an influencer who once traded (and sucked at it).
Taleb made a lot of money trading, his firm failed but running a successful business is not trivial and his ideas ended up working when he took up an advisory role rather than an executive role. Unlike other financial "influencers", he actually seems to understand mathematics to a high degree. Hardly your typical economist op ed writer.
No skin in the game, as it were.
