I think you’re missing the point of Dune. They had their Butlerian Jihad and won - the machines were banned. And what did it get them? Feudalism, cartels, stagnation. Does anyone seriously want to live in the Dune universe?
The problem isn’t in the thinking machines, it’s in who owns them and gets our rent. We need open source models running on dirt cheap hardware.
The point of Dune is that the worst danger are people who obey authority without questioning it.
