Three and four are both non-zero numbers. Zero constitutes the absence of value. Therefore, three and four are of the same value.

You see the problem here, right? I'm not saying that fungi have not be recorded as having potential intelligent thought. I am saying that in no world is their capability for intelligence remotely comparable to that of a creature with a fully functioning brain, especially a bird. Having the ability to react to your environment does make you AS or more intelligent than other things that can also do that...

EDIT: I'm using intelligence and consciousness interchangeably here when I don't necessarily mean to, but my point stands.
