I heavily disagree here, chat - or really text - is a horrible UI for image generation, unless you have almost zero idea of what you want to achieve and you don't really care about the final results.

Typing "make the bar a bit more like a fizzbuzz" in some textbox is awful UX compared to, say, clicking on the "bar" and selecting "fizzbuzz" or drag-and-dropping "fizzbuzz" on the "bar" or really anything that takes advantage of the fact we're interacting with a graphical environment to do work on graphics.

In fact it is a horrible UI for anything, except perhaps chatbots and tasks that have to do with text like grammar correction, altering writing styles, etc.

It is helpful for impressing people (especially people with money) though.
