It's strange to me too, but they must have done the market research for what people do with image gen.

My own main use cases are entirely textual: Programming, Wiki, and Mathematics.

I almost never use image generation for anything. However its objectively extremely popular.

This has strong parallels for me to when snapchat filters became super popular. I know lots of people loved editing and filtering pictures but I always left everything as auto mode, in fact I'd turn off a lot of the default beauty filters. It just never appealed to me.
