OpenAI said it will discontinue Sora, the generative-AI video creation platform it launched in late 2024, without providing a reason for the decision.

That is the strongest indication this is the beginning of the end for the AI bubble. Sora burned a ton of processing power, with no clear value proposition, just to keep the hype cycle going a little longer. Shutting down without explanation leaves the most likely one: they are out of helium to pump into the balloon. And if that balloon isn’t inflating, it’s deflating.
