This is a good commentary that links to the article above: https://futurism.com/artificial-intelligence/deutsche-bank-grim-warning-ai-industry
The tl;dr is that the amount of money spent on capital expenditure (building server farms and chips) for AI has exploded, but it has not brought the concomitant revenue growth to make it sustainable. AI capex is now responsible for more GDP growth than “all of consumer spending combined.” To pay for this, the AI industry needs to generate more than $2T *annual* revenue by 2030, which is ludicrous. Sooner or later, the piper must get paid.
