So much for making assumptions about the consciousness of others!He's made it pretty clear he objects to other viewpoints. He had a knee-jerk reaction to a perceived sleight about philosophy, and only saw red after that. That's OK; he's only one of many voices in this discussion.
As you said, we learn more about our world by assuming everyone else is as conscious as we are. In the same way, we proceed as if we are not brains in a vat, or programs in a simulation.
Society would proceed at a snail's pace if, everytime we communicated with someone, we had to ask if their words were merely the product of a complex chatbot.
Claiming that something is "purely philosophical" is a common way to dismiss both philosophy and an issue. Perhaps you are ignorant of this, despite equating philosophy and the issue with "no material difference". Perhaps you projected your own anger on me.
