Technology is rapidly changing these days as the number of developers and companies increases at a surprising rate. It definitely makes sense from a progressive societal standpoint. The more people you have working on a particular field, the more likely it is to evolve and to change, for a few basic reasons. For one, more and more people are beginning to look forward towards the future of that product, which of course always causes the future to eventually get here. And once it does get here, we'll have something that didn't exist before mingling with a bunch of stuff that did exist previously. If you're someone who started their career before that initial alpha moment, then the change is much more noticeable.
