It seems kind of like how incorrect news about science becomes “common knowledge”. This person probably saw someone else post this, and now they’re just parroting it back. That other person, they might have had it from a news article. Or maybe they were just parroting another comment in turn. Even if it was from the news, was that news sources from a sophisticated engineering perspective, or a bit of marketing fluff? Hard to know. Not saying whether this is correct or incorrect either, just making a comment about the sources of knowledge in general in the age of internet comments.

But it would be pretty quiet on here if people only talked about what they actually know.
