Penrose vs Quantum Mechanics vs Consciousness

2020 Nobel Physics Laurate Roger Penrose claims that 

1. Quantum mechanics is inconsistent (=wrong).
2. Consciousness is governed by quantum mechanics.
3. AI is impossible.
4. There has to be something in physics that we don't yet understand, which is very important, and which is of a non-computational character.

Hopefully Penrose can elaborate on these themes in his Nobel Lecture.
