"there is evidence" - Translation: He read a sensationalist headline somewhere about a single study, didn't read the study, definitely didn't look for corroborating or refuting studies, and absolutely, positively has no actual data to confirm his pet theory.

This is literally the dumbest interpretation of the concept. This is what it looks like when tier-1 tech support folks want to roleplay as ML engineers while they troll internet forums cosplaying that they're somehow "helping" while doing absolutely nothing meaningful with their life.
