I will say, I find it fascinating that there are some philosophers and consciousness researchers who seem to be less certain. I just listened to Chris Hayes interview David Chalmers this week, whose position seemed to be that it's probably not conscious, but that we can't be certain. And more than that: he seemed open to the idea that they may become conscious under further scaling/training/advancements.

It's a great interview, if you're interested: https://www.youtube.com/watch?v=NgDIG8u1-CA
