I agree. Under QI it's possible we end up as some disembodied conscious matter in a state of eternal agony; QI only says consciousness will persist, it says nothing about quality of life.
When we die, our consciousness just gets transferred over to the atoms that make us up. Since there is no longer a self-contained "vessel" for it, specifically a hippocampus, we don't have any short-term or long-term memory anymore, but are still experiencing. That's why we can't remember time before we were born.
