50 years ago you could work on a brand new car with just the tools in your garage, now you'd need specialized knowledge, equipment, and more to the point that it's not really possible to be a home mechanic on many areas.
This isn't new for new's sake, these improvements bring real benefits. And as things get more complex, people will specialize more and more. In the future, your average "dev" might not know the ins and outs of how the transport layer works, but that's okay because there is someone else who mainly only does that.
