pre-echos of "too big to fail"

I’m not sure I understand these references. The banks were too big to fail specifically because they were banks involved with the finances of every major industry and government, not simply because their (arguably specious) valuations, or even market caps, had a ton of zeroes on them. What’s the argument for OpenAI being so inherently critical and interweaved with the rest of the economy that it can’t be allowed to fail? What’s the argument for how such a bailout would result in greater economic outcomes? The banks that got bailed out continued lending and immediately resumed profitable business, how will the AI companies offer value towards such a proposition?
