The question has been eagerly discussed the last 1-2 years. Are there enough revenue to justify the huge investments or not.
Now two CEO's heavily involved in the AI investments has expressed thougths which imply that the risk may be real.
Andy Jassy, Amazon (via TheRegister):
"I think it could end well," the Amazon CEO said. However, "anytime you make substantial investments … not all of them are successful. And the hit rate is pretty variable."
Satya Nadella, MicroSoft (via Futurism):
“For this not to be a bubble by definition, it requires that the benefits of this are much more evenly spread,” Nadella said, as quoted by the FT. The “tell-tale sign of if it’s a bubble,” he added, would be if only tech companies were benefitting from the rise of AI. He gave the example of a pharmaceutical company using AI to accelerate drug trials; it doesn’t need to be used to discover the “magical molecule,” but provide some other tangible, less extraordinary benefit to developing the product.
