With all respect you didn't debunk anything. Some physicists believe consciousness has something to do with collapsing the wave function. A majority presently believe as you say that it could be a measurement device that does so. At this point nothing has been proven with absolute certainty.
As Richard Feynman said "If you think you understand quantum theory . . . you don't understand quantum theory."
Why be so insistent that you are right that you can't even comprehend why someone wouldn't have made up their mind yet?
I certainly do not claim to be any expert on quantum theory. Are you an expert?
