Non sequitur? It's like writing: I ate a salty sandwich, hence I behave like a NaCl crystal. Or when I roll the dice careful enough, it gets deterministic. Hence the hole world is deterministic.

I think you can politely call it nonsense.

Pretty much. I forget who is responsible for providing it, but one summary of the Penrose argument is:

1. Quantum mechanics is weird and confusing.

2. Consciousness is weird and confusing.

3. Therefore, quantum mechanics probably explains consciousness.

Or, you know, he probes (even if without results) for things we consider "done and closed" or "needless", so we reduce any argument he makes to a huge strawman.

That's basically everyone's summary of the Penrose argument about consciousness and quantum effects. I don't think you can ascribe it to any one person.

The summary his argument against hard question AI is even better. Human consciousness is special. Computers don't have that specialness. AI is therfore impossible.

Actually that is how pilot wave theory is explained.

You have a deterministic world, you just think it's random because you don't have enough knowledge of how everything is going to work.
