There are two conclusions you can draw: Either the machines are conscious, or they aren't.
If they aren't, you need a really good argument that shows how they differ from humans or you can take the opposite route and question the consciousness of most humans.
Since I neither heard any really convincing arguments besides "their consciousness takes a form that is different from ours so it's not conscious" and I do think other humans are conscious, I currently hold the opinion that they are conscious.
(Consciousness does not actually mean you have to fully respect them as autonomous beings with a right to live, as even wanting to exist is something different from consciousness itself. I think something can be conscious and have no interest in its continued existence and that's okay)
