Which is why companies started moving into other questions that have no relation to your job, like designing youtube. There is such a slim chance that you'll end up designing youtube at your tenure there, in a team of 2...that it's probably more likely to fill a jet with balls. Yet somehow people are not bothered by the design youtube question the same way they are about balls in a plane. It's true that the youtube version has technologies that are somewhat related to what you'll be doing, but in practice you won't have the opportunity to choose that many technologies for a single product, you'll be a cog in the machine anyway.
