I've read through this article twice and I can't put my finger on it, but there is something about the "sample population" that is bothering me. No mention of where those sampled are from, no mention of profession, but an emphasis on a couple of online groups. This just seems like a poor sampling to make a study off of. If you were to take a mix of millennial and older technologists in the bay area, you would likely find some interesting overlaps (probably way more in tune than the study is showing) that are completely different if you took a sampling of a general popular somewhere in middle america even if both groups were "active online".
