The thing is this really depends on the speed of some financial events, not some technical failing.
Notably, if OpenAI has to cancel any of their commitments to buy hardware because they find they have neither the money nor can secure even more debt to cover, that event would potentially cause the bubble to pop, even for hypothetical companies that may have been more responsible and might have a viable business approach. Those commitments are coming up, and a lot of analysis struggles to see how they will fund those commitments.
The thing with this bubble is that the investors don't get the nuance and will flee at signs of trouble in any of OpenAI, Anthropic, or a handful of others, and Altman's leadership has made trouble at OpenAI very likely, but the investors don't believe it and won't believe it's unique to OpenAI, even if it would be.
YouTube started in 2005, but was not really a "streaming service", it hosted random internet posted videos. The concept of engaging with the big content rights holders wasn't remotely in sight back then.
Hulu came out a year after Netflix started streaming, by about a year. Hulu was inspired by Netflix's move to have actual traditional media content as a streaming service instead of ad-hoc video uploads like youtube.
RealPlayer offered technology for websites to provide videos, they themselves I don't recall being a streaming platform in and of itself.
Whatever one may say about Netflix, they were right there in the beginning with streaming traditional, professional media content. Yes, video playback over the internet wasn't new, but that's a technical detail that enables, but is not the core of the "streaming service" business model.
