Not coincidentally, this results in massive overspend until someone notices and has to painstakingly go round checking what all your instances are for. And AWS is very profitable (well, margin rather than accounting profit).
Now, look at the billing model of AI, especially once flat rate goes away. People can spend millions on tokens without ever having to ask a manager! Obviously this is going to rake in money hand over fist, because it will be years before anyone catches up to ask "are we actually getting value for money here?" rather than "quick spend more tokens".
This point is underappreciated as it appears in many forms and can really help reconcile things that seems obviously wasteful (they may actually be wasteful, but sometimes financial structure makes this hard to determine in an honest capacity).
Capital costs and operational costs are a similar dichotomy. When I was in graduate school, the university was breaking ground on new buildings at the same time that staff layoffs were underway. On its face this seems grossly unreasonable, but staff salaries were paid from one funding bucket and capital improvements (new buildings) were funded by a completely independent state-level allocation process and those buildings that were breaking ground had essentially been locked in 5 to 10 years prior.
