Yeah yeah yeah, probably exploiting capacitance instead of on-spec functionality, I'm well familiar with this example. It's not relevant - there's eight billion human brains in the world, and they generally still function despite the wild shit we put them through. They are not fragile.

A human mind is not balanced on a knife-edge, where one tiny difference breaks everything. They're complex enough that sometimes blowing a railroad spike clean through just alters functionality. It's still a mind. Subatomic interactions surely cannot be crucial here.

And again, this is only the extreme example. Y'think all known laws of the universe are mandatory? Great, simulate those too. Same answer: meat has no monopoly on thought because metal can fake the meat. There is no philosophical basis for even suggesting AGI is impossible, unless you start talking about souls.
