A little history When looking for the best learning investments, I like using wise business principle practiced by Jeff Bezos: I very frequently get the question: 'What's going to change in the next 10 years?' And that is a very interesting question; it's a very common one. I almost never get the question: 'What's not going to change in the next 10 years?' And I submit to you that that second question is actually the more important of the two - because you can build a business strategy around the things that are stable in time. On the surface technology is advancing extremely fast, but most of it is powered by fairly stable foundations and a quick dive into history may reveal one of them.
