Off topic, but I Googled "argon powder" and the AI overview thing hallucinated that the term means metal powders used for 3D printing, stored under argon to prevent oxidation. There are no actual results using the term in that sense, as far as I can tell.

Google search should not be returning an incorrect hallucination that sounds plausible ahead of the actual search results. It's so confidently wrong. Google is SO BAD NOW at searching for specific expressions.
