Yeah, this paper is time wasted. It is hilarious that they think that 3 years is a long time as a data scientists and this somehow gives them such wisdom. Then, they can't even accurately extract the data from the chart that they posted in the article. On top of all this, like you pointed out, they can't even keep a clear narrative, and they blatantly contradict themself on their main point. They want to pile drive people who come to the same conclusion as themself. What a strange take.
