As an "outside observer", I think maybe you're not seeing (what I believe is) the other guys viewpoint: What you are bringing up (photoshop has been possible already) is a core part of what he said from the start, and his point builds on top of that. So obviously he already knows it, and arguing about it disregards that his line of argumentation builds upon the basis we all agreed upon to be true until you brought it up as ... contrarian? To his point. doesn't seem like "old man yells at cloud" energy, more like "Uhm, achtually"
