Hedge fund manager David Einhorn warns of extreme spending in the AI field or potential great capital losses.

Hedge fund manager David Einhorn warns that while artificial intelligence technology itself is revolutionary, unprecedented infrastructure spending on AI could potentially destroy a significant amount of capital. The founder of Greenlight Capital says that the overall investment of tens of trillions of dollars by companies like Apple, Meta Platforms Inc., and OpenAI is too extreme, with highly uncertain returns. While he expects AI to eventually surpass current optimistic expectations, he also questions whether investing "1 trillion or 500 billion dollars a year" will bring good returns to the companies making these investments.
