That was happening even when they were still calling it machine learning in the papers. Longer before that still. It’s the way some people reliably get papers out for better or worse. Find a known phenomenon with existing published methods, use the same dataset potentially using new method of the day, show there’s a little agreement between the old “gold standard” and your method, and boom, new paper for your cv on $hotnewmethod you can now land jobs with. Never mind no one will cite it. That’s not the point here.
