Very informed article discussing the nuances of the situation. It's not as straightforward as many think. You're right saying that things don't have to work the same way as last year. For example, technology is advancing all the time, and evolving. No sooner is one software framework developed than there is yet another and so on. Having studied in this area, I'm aware of how quickly things become obsolete. Thanks for discussing the nuances in greater depth, as I am sure they will help others make more informed decisions.
