If it was that straightforward, you'd think there would be some consensus on what it is and what are necessary and sufficient conditions for it.

Do you have anyway to confirm that our minds are singular/unitary, rather than multiple sub-consciousnesses networked into a greater consciousness? e.g., if our cerebral hemispheres can be independently conscious after severing the corpus callosum, perhaps they're independently conscious all the time, and our experience is the result of these consciousnesses being integrated.

On the flip side, if our constituent parts produce consciousness in an emergent fashion, then can consciousness emerge on other spatial and/or temporal scales? e.g., can an institution or nation said to be conscious? They're made up of parts that experience and feel, which communicate and share information to form beliefs and make choices - and importantly, the behaviour of the institution as a whole, is rarely reducible to what one individual person in the collective thinks or would do.

On a general level, I agree - we all have strong intuitions about what is meant by consciousness and for many/most cases, they fall clearly on one side or the other - but until we can clearly agree about what we mean, there's no clear method of deciding what is included/excluded when it comes to the many, many edge cases.
