In the case of frontier AI, humanity knows less about what we’ve built than we know about airplanes *or* birds. LLMs almost completely fail to satisfy the primary *original* motivation for AI research, which was to advance the science of human cognition.
Airplanes do not need flapping wings in order to carry people and goods through the sky, but they *would* need flapping wings in order to convince someone that humanity actually understands how birds work in enough detail to build an accurate fully functional bird from scratch.
