As I think about our bailing out Detroit, I can’t help but reflect on what, in my view, is the most important rule of business in today’s integrated and digitized global market, where knowledge and innovation tools are so widely distributed. It’s this: Whatever can be done, will be done. The only question is will it be done by you or to you. Just don’t think it won’t be done. If you have an idea in Detroit or Tennessee, promise me that you’ll pursue it, because someone in Denmark or Tel Aviv will do so a second later.

Why do I bring this up? Because someone in the mobility business in Denmark and Tel Aviv is already developing a real-world alternative to Detroit’s business model. I don’t know if this alternative to gasoline-powered cars will work, but I do know that it can be done — and Detroit isn’t doing it. And therefore it will be done, and eventually, I bet, it will be done profitably.

And when it is, our bailout of Detroit will be remembered as the equivalent of pouring billions of dollars of taxpayer money into the mail-order-catalogue business on the eve of the birth of eBay. It will be remembered as pouring billions of dollars into the CD music business on the eve of the birth of the iPod and iTunes. It will be remembered as pouring billions of dollars into a book-store chain on the eve of the birth of Amazon.com and the Kindle. It will be remembered as pouring billions of dollars into improving typewriters on the eve of the birth of the PC and the Internet.
