I'm really sad about how little creative control these tools have. They seem great for creating slop, but pretty useless for creating content that someone would love. I love the potential but text isn't really a great medium for describing artistic vision.
All these demos are focused on how easy it makes everything. Easy is great, but if everyone is able to make instant cute cat videos or whatever it just devalues it. I want to see turning a photo into a rigged 3d model, letting the artist animate and then generate the video. This technology could be used to increase creative expression, but instead it's being used to squeeze out creative expression
