Appreciate the work done by the researchers! Designing model architecture has been a hot topic. Building machine learning models is sort of like a repeates experiment - finding appropriate data sources, feature engineering, using different models and again and again. It will for sure be good to have a single model which can produce reasonably good results on a wide range of data set with various data structure to save much time on the work!
Perhaps one day, we can feed machines with all the knowledge we've accumulated, and let it generate more knowledge/innovations that could solve problems we find impossible right now and into the future.
Definitely agree with you!
