According to CoinMeta, Bezos stated that it is currently difficult to determine whether artificial intelligence is in a bubble, but he believes that the technology itself is real, despite investors funding projects of varying quality. He pointed out that tech booms often lead to capital flowing into almost all experiments, making it difficult to distinguish between sustainable businesses and speculative ones in real time. He warned that some investors may suffer losses due to overly high expectations, but this does not deny the value of the underlying technology. Bezos mentioned that major tech companies have invested tens of billions of dollars in artificial intelligence infrastructure, yet the returns on that investment are still uncertain. At the same time, AI-related companies account for a large proportion of the S&P 500 index, increasing market exposure to this topic. As for whether retirees should buy individual AI stocks, Bezos suggested investing in the S&P 500 index, as it already provides exposure to major AI companies without the need for investors to pick individual winners.
