This is a reductive argument that you could use for any role a company hires for that isn't obviously core to the business function.

In this case you're simply mistaken as a matter of fact; much of Anthropic leadership and many of its employees take concerns like this seriously. We don't understand it, but there's no strong reason to expect that consciousness (or, maybe separately, having experiences) is a magical property of biological flesh. We don't understand what's going on inside these models. What would you expect to see in a world where it turned out that such a model had properties that we consider relevant for moral patienthood, that you don't see today?
