Sometimes I get myself into a reading obsession that can’t be quenched. In the last few weeks, that’s been delving back into the world of Silicon Valley and the technology startups that have so radically changed our world. The best tech companies manage to manifest the future they’re predicting; the worst present us with an Oz-like illusion that leaves us not only disappointed, but permanently jaded too. After the likes of Theranos, WeWork, and even over-valued Uber, it’s hard to envision any company following through with their lofty ideas.
