Ha ha, you must not be aware of graphics tools like Blender, Maya, Rhino, Krita, SolidWorks, etc, or games like The Sims, Secret of Mana, Neverwinter Nights, Crysis, Mass Effect, Battlefield, etc.

"Hard to understand" is on you, buddy. I wasn't aware that "everyone" got together and agreed on everything -- that seems like a suspicious claim. Where did you read that? Surely you can cite some papers and article by "everyone" as evidence, and you're just not making it up in an attempt to troll.
