I find it mildly silly that some people in tech are still talking about whether "artificial intelligence" tools work or not. For their cost it would be irrelevant even if they worked. Did you actually look at the numbers of the companies involved? Oracle has now a >4 debt/equity ratio, CoreWeave has almost 9. Values above 2 are considered abnormal and dangerous. This is the financial equivalent of smoking in a factory that produces explosives.
