Looking at the case where khanacademy is migrating their server only after about 10 years. I realize more that I don't have to worry that much about being locked into certain technologies (unless it's clearly untransferable, e.g. storing part of customer data in 3rd party server), because after all, we might keep it only for about 10-20 years, and the thing I'm working at almost certainly will only last < 2-3 years.
