This is a pretty poor article. Yes. Cleantech was bad for Kleiner Perkins and a lot of other VCs that bet on it. But it also didn't work out for large companies, governments or research groups investing in it either. Many of the arguments made here could equally well be applied to life sciences, but life science and biotech VCs have seen reasonable returns in investments and their LPs are often large pharma companies. Also the author seems to be clueless as to the fact Moore’s Law is nothing to do with the speed of company growth but rather to do with the performance of computing power. While their might be certain products that require an investment structure that VCs can't provide, this article fails to make any kind of coherent argument for it.
