I think Sora was technically impressive as a concept. The way it was managed as a product wasn't good.
There didn't seem to be any marketing for it. Like I can't even remember an ad for it or any content creator type of person pushing Sora actively.
To get access to Sora I believe you needed to be on a paid plan?
It's really difficult to get user generated content going when it's behind a paywall.
It's also hard to tell if this means that openai is in trouble, or if this is just a badly managed product that deserved to be killed. With the negative sentiment on openai, folks might think the former.
