My geology professor once tried this with a pixelated image of granite during an online lab. I can barely tell quartz from feldspar when it's in my hand, let alone on a blurry screen. The lighting in phone photos always washes out the key details like crystal structure or color. When my manager pushed for it, I just nodded along while secretly guessing based on the rock's shape. It turns out our team called a piece of slag 'obsidian' for three weeks. The whole thing feels like trying to diagnose a car engine from a sound clip.
This happens everywhere now, from tech support to medical advice. People act like a quick photo fixes everything, but it just makes guessing look like expertise. We're all just nodding along while the slag gets labeled obsidian.
