Seems kinda over the top. Not everybody has design chops, nor artistic abilities - never mind the event itself should be the focus, not how all the myriad promotional details are put together. What's more important to focus on?
ETA: Don't get me wrong: what they're passing off as "AI" sucks in so many ways, but it can be useful in areas not requiring reliably factual output. Outside of having briefly tried it a few times in the past, I don't even use it myself.
EDIT 2: I'm done here. I've made my points in several ways across numerous comments, and too many of you seem incapable of looking at things objectively. Latecomers with an open mind are welcome to read my comment history to see what I'm talking about, but I will not be responding to all the closed-minded angry mob types anymore. There's little more I can say that I haven't already.
