Not at all. It seems obvious to me that the robot functions independently and can trigger its bits and store memory without the engineers. It is obviously conscious to some degree. The disembodied neurons in your previous example cannot trigger its bits and store memory without the engineers. It is obviously an inanimate object.

It does indeed come from the biochemical activity of the meat machine. However, you have dismantled the meat machine in your previous example. Even though all its parts are still available, they are no longer functioning together as a system. Machines stop functioning when they are dismantled. This disembodied "brain" cannot answer questions or hold secrets separate from the engineers. Any thought or function you ascribe to it must first be performed by the engineers and then "credited" to the disembodied brain.
