There was a good quote after uBeam (wireless charging) was called out by engineers for their physics being highly dubious: <a href="http:&#x2F;&#x2F;techcrunch.com&#x2F;2015&#x2F;11&#x2F;07&#x2F;wireless-power-charger&#x2F;" rel="nofollow">http:&#x2F;&#x2F;techcrunch.com&#x2F;2015&#x2F;11&#x2F;07&#x2F;wireless-power-charger&#x2F;</a><p>&gt; “People are saying that investing [$23.4 million] into uBeam is everything wrong with Silicon Valley” uBeam co-founder and CEO Meredith Perry tells me, referencing her startup’s big name investors. They include Andreessen Horowitz, Founders Fund, UpFront Ventures, Marissa Mayer, and Mark Cuban. “But everything else out there is apps and social photo sharing stuff” Perry contends. “We’re building something real. We’re building something that’s insanely difficult. So difficult people think that we’re frauds.”<p>It&#x27;s surprising that startups get <i>less</i> scrutiny for hitting hard problems. You&#x27;d think it would be the opposite.
