Gate News reports that on March 19, according to 1M AI News monitoring, Y Combinator co-founder Paul Graham shared a conversation with an OpenAI employee on the X platform. Graham mentioned that buying rare vintage items can hedge against AI risks because AI cannot go back in time to create them. The other person responded, “Anything made before 2028 will be very valuable.” This statement implies that after 2028, AI will be able to create most of what humans can create, and only items created before then will retain value due to their irreplaceability. Graham interpreted this as the other party “unintentionally revealing their timeline.” He added that he doesn’t pay much attention to specific years, but “the general idea is quite interesting.”
