If that's what production was about, humanity never would have left caves.

The ancestors of the fix-pie idea were the ones who would have sneered at the first hut built outside of a cave, at the first crops deliberately sown into the ground, at the first villages built up to provide better living conditions for groups of people including as a trade center.

Everything from 100,000 years ago to today is the result of productive human beings who made more of the world. It's an ongoing process.

Is the engine honest enough to reality to demonstrate failure?

Birds are alive, are conscious, flap their wings, and fly. Planes are not alive, are not conscious, do not flap their wings - and fly.

Similarly, current AIs are not alive, are not conscious - but think.

All prior entities that thought, were human, so the only experience humans had with other thinking entities were other humans. The huge mistake now being made is assuming that because they think, they're alive and conscious as well. Current AIs are neither, and are therefore profoundly and qualitatively different than humans - even though they do think.
