Literally just mainlining marketing material straight into whatever’s left of their rotting brains.
That’s an unfalsifiable belief. “We don’t know how sentience works so they could be sentient” is easily reversed because it’s based entirely on the fact that we can’t technically disprove or prove it.
There’s a distinction between unfalsifiable and currently unknown. If we did someday know how sentience worked, my stance would be falsifiable. Currently it’s not, and it’s fine to admit we don’t know. You don’t need to take a stance when you lack information.
