Well believing his room looks like that would be knowledge, because the room would look like that.
If it was about the background being the actual room, then the justified belief wouldn't be true.
I think the whole point is that the difference between belief and knowledge isn't about whether or not you're right, it's about whether or not your belief has been verified and proven to be true, so in OP's example, they would be right that the room looks like that, but that belief wouldn't have been verified due to the professor never seeing his actual room. Thus, a justified true belief, but not knowledge.
I agree and understand.
And technically, sort of, yeah. I don't have a certain answer, but this is exactly what epistemology deals with.
But I think this is just sort of conflating some things for humour a bit. Humour often relies on slight leaps in "actual" logic. It's definitely close enough for a joke, I'm just pedantically discussing whether it's technically epistemologically correct, if such a thing can even be determined.
It sort of is. Both are beliefs, but knowledge is something that's a true belief, but also, it has to be justified. So for instance believing that antibiotics help infections isn't necessarily knowledge if your justification for having that belief is "there are miniature soldiers in the pills who fight viruses with laser guns", then it's not knowledge. Especially because antibiotics affect bacteria, not viruses. If your justification is correct though, then it's a justified true belied, and thus constitutes knowledge.
But here if the knowledge is "that is how his room looks like", it would be a true belief, but then it wouldn't be justified, because it wasn't actually the room they were seeing. But the joke I think relies on the fact that technically it is justifiable because seeing someone's room (or a projection of their room) is in everyday practice justification enough to believe what you see. But is it that philosophically? Or if it's "I'm seeing his room right now", it would be justified, but not true?
Btw I'm not making an argument, I'm making conversation.
I would say that the meme does a good job of producing a Gettier Case, which many philosophers recognize as valid counter examples that disprove the Justified True Belief definition of knowledge, indicating that a complete definition of knowledge requires more than those three elements.
Philosophers (aside from skeptics) were mostly agreed on JTB as a straightforward and elegant definition of knowledge for most of history and they have struggled to reach a new consensus after Gettier and instead are left with a hodgepodge of competing definitions. This could be perceived as something that might frustrate a philosopher, and that I think is why the meme positions this as a sort of "prank" for philosophers.
