The "hard problem" is how it is possible for anything to "look like" or "feel like" anything in the first place. Not only do we not know how to simulate that, we don't even know how to sense that it is taking place in anything other than our own minds.
But that’s the same kind of situation as figuring out how windows draws the solitaire on the screen.
Imagine that you lack all context about computers. You are intelligent, but grew up on a desert island. Then a boat arrives. You see a sailor taking pictures with their iPhone. You don’t even know what you are looking at. “What is a computer and how does a computer work” would take years to explain. The same goes with “how does a screen work”. Etc.
At the stage we are, asking “what is conscience” is like that hunter gatherer asking “how does the little box show my friend’s image inside”. The answer is going to be “let me give you some context first, you are missing too many pieces”.
We just need more pieces. But that doesn’t mean that it is hard. When you are missing lots of pieces, knowledge grows slowly, usually.
