An important thing to keep in mind when Larry Page is going on about "investing in the future". Relevant Buffett quote: Evaluating that company is within what I call 'my circle of competence.' I understand what they do, I understand the economics of it, I understand the competitive aspects of the business. There can be all kinds of companies that have wonderful futures but I don't know which ones they are. I've given talks in the past where I carry with me a 70-page tightly-printed list, and it shows 2000 auto companies. Now if at the start of the 20 th century you had seen what the auto was going to do to this country, the impact it would have on the lives of then your children and grandchildren and so on. It just, it transformed the American landscape. But of those 2000 companies, three basically survive. And they haven't done that well, many times.
