r/MachineLearning - [D] Data research: the new direction?

Recently I am working on projects that deal with datasets directly. What I found is that there is so little research on data such as data annotation, though there is a lot of work on semi-supervised learning, and more recently, self-supervised learning. In my opinion, the research community will gradually move from a model-centered research to data-centered research. I wrote an article to discuss this on Towards Data Science. I'd really like to hear you guys' opinions
