Ed Zitron has a piece out talking about how even if Anthropic and OpenAI are bringing in revenue, most of it is coming from startups in such a way that their revenue will evaporate if the underlying startups crash, especially because the underlying cost of operating remains high (and where improvements in the underlying tech go towards improving performance rather than making operations cheaper).
To me, it's a pretty persuasive argument that failures at any one part of the web of businesses and funds involved (even if completely unrelated to the AI industry) will cause stress on all of them, because they're so interrelated in a web of relationships.
