There is a difference between getting an education and being educated. If you focus on educating yourself without worrying about what your title you have the chance of learning about subject matter transcendence i.e. you will become skilled at some mixture of subjects without being "the best" at any one of them.
This subject matter transcendence I believe is one of the keys to staying relevant and aware of what is going on around you as it gives you an intuitive understanding of how various areas could be connected.
As typical example is the designer/developer. A person who both know how to design and how to code. That person might not be the best at the individual disciplines but the combination is in itself providing them with an edge on 80% of the people BOTH in the design field AND in the development field.
Don't worry about confining yourself into becoming an expert in one field who then will need to compete with other experts.
Instead become an expert in your own chosen subject matter no matter how fractured and you will be able to if nothing else, start your own company solving a problem your unique understanding of the world might lead you to.
In other words. Don't worry just keep educating yourself that's the best you can do.
