Confused by Wall Street? Join the club. Vinod Khosla, a venture capitalist who is one of Silicon Valley's most revered brains, doesn't get what's happening, either. "If I can't understand it, I suspect a lot of people can't," he told's Andy Plesser in this video interview. "In the name of economic efficiency by slicing and dicing risk, we're reducing transparency, which is not a healthy thing." I was with him that far. But then he concluded: "Venture capital will be a pretty good place when we return to reality and invest in things we understand and are real." That rules out most Web startup investments made in the past couple of years. Heck, Khosla believes in cost-effective ethanol.
