You are confusing intelligence with consciousness (qualia). We simply don't know how qualia develops or how to measure it. We cannot discard, for example, than an ant has a greater qualia level than us. There are theories about qualia being connected to microtubules on neurons and quantum effects... the DOOM-playing neurons also have those microtubules. So you cannot say "definitely not".
> consciousness (qualia)
I've never heard the word qualia used as a synonym for consciousness, only as a related but distinct concept.
> an ant has a greater qualia level than us
What? where does this come from?
