as a game designer I can promise the future of gaming has a lot in store for you :) We are still in the tech-rush era where game development is mostly focused on exploiting new technologies and marketing to trends, but this is coming to a close shortly after VR and then the real games begin. In the near future, companies won't be competing on the same grounds as they are today, it will be almost entirely a contest of design and the engineers working on the engines won't have to constantly be learning new technology, they will instead be spending many years mastering the very advanced technology being developed right now! It's going to be magical, you picked the best hobby :)
