An alarming number of Hollywood screenwriters believe consciousness (sapience, self awareness, etc.) is a measurable thing or a switch we can flip.
At best consciousness is a sorites paradox. At worst, it doesn't exist and while meat brains can engage in sophisticated cognitive processes, we're still indistinguishable from p-zombies.
I think the latter is more likely, and will reveal itself when AGI (or genetically engineered smat animals) can chat and assemble flat furniture as well as humans can.
