"Meanwhile, Pakistani immigrant Dinesh spectacularly screwed up both a CEO position and a relationship."
Dinesh is perhaps the most likeable character on the show. Yes, he messed up in the CEO role. Just like Richard, and Gavin Belson, and the other CEO of Pied Piper. Just like Erlich and Big Head in running their incubator. Has the author actually watched the show?
Regarding Dinesh's relationship, he ended it, for good reason. Contrast that with Richard's recent experience.
Jian Yang is an immigrant, and Erlich's frequent references to that fact can be grating. But the argument that Jian Yang's bad app idea is racist is ridiculous. People in SV pitch bad ideas all the time. Is the author suggesting that non-white characters can't be shown failing?
