We have no idea what consciousness is.
Literally. It’s something that we all experience, but there is no scientific definition, measure, or framework to study it.
We assume it is a function of our brains, but we could be wrong. Are intelligent birds, apes, and dolphins conscious? What about lizards? Flatworms? Trees? Yeast?
If you want to go down that rabbit hole, search “what’s it like to be a bat?” or “the hard problem.”

















It’d be great if any part of that were testable.
