The first game I ever bought with my own money was Metal Gear Solid 1. And the PS1 to play it on.
I wanted FF7 but they didn't have it. But MGS was a good second choice. It was also the first time ever buying anything from a second-hand store. I wish I could remember the name of the store; it wasn't Funcoland or EB. They had a logo that was an anthropomorphic SNES cart, tho.
I think using AI for storyboarding is okay. They are already pretty shitty, quick af sketches used to figure out how to arrange the action and get animators on the same page. Now that can be done just a little quicker.
However, using them as placeholders that could end up in the final thing even accidentally, is dumb. A placeholder doesn't even need to be representative visually of what it's holding a place for. Textures could be text that says "texture of wood 1" and words can be normal ass Ipsum Lorem.
