Quantum physics isn’t shenanigans, it’s completely fundamental and necessary to the brain and its electrochemistry. To say “yes but we can create a model of the brain which doesn’t need all that, we can model the classical physics or a reduced set of quantum interactions (running classically)” and then model the brains neurons on a computational substrate, well this is going to be nothing like the brain so won’t give you the result you’re looking for.

And say what you want about meat but we don’t seem to find consciousness in rocks or plants or clouds or hairdryers. And the buddists report that some very strange things happen if you meditate for years on end but obviously they must be talking shit and making it up because it’s not testably scientific.

Totally agree. There's nothing magical about meat.
