There absolutely is a hard problem of consciousness.
One thought experiment I like to use to illustrate this: Imagine we accept that an AI is conscious, in the same way a human is.
Now, what defines the AI? You might say the algorithm and the trained weights. Ok, so let’s say, in a similar way, we extract the relevant parameters from a human brain and use that to craft a new human.
Are they the same person, or two? Do they experience the same consciousness? Would they share the same embodied experience?
Could the one be dead and other alive? If so, what makes them have their own individuality? If your loved one died, and their brain was reconstructed from parameters stored while they were alive, would you accept that as a resurrection? Why or why not?
Note that I offer no answer to the above questions. But trying to answer them is part of what the hard problem of consciousness is about.
