>...you can't do ROI calculations on that. Instead, you dump as much money as you can into it, and then you know that decades down the line, you'll be very happy that you did it. I could apply this quote to all kinds of other ways of spending money, and it would hold true (e.g. infrastructure or social programs). And while you can't do ROI calculations on long-range programs, you can make informed decisions about which are more likely to provide the greatest benefits. In fact, if you are talking about spending billions of dollars of other people's money, you have a moral and ethical obligation to do exactly that.
