What do Sam Altman and David Sacks have in widespread? Definitely not politics. Mr Altman, co-founder of OpenAI, is a part of the transition crew of Daniel Lurie, the Democratic mayor-elect of San Francisco. David Sacks, an entrepreneur and polemical right-wing podcaster, will on January twentieth turn out to be Donald Trump’s crypto and artificial-intelligence (AI) tsar. But each have the excellence of being amongst Silicon Valley’s finest spotters of entrepreneurial expertise. In keeping with knowledge from TRAC, a venture-capital (VC) agency, few are nearly as good at selecting promising startups on the very earliest stage.
