This is going to sound a bit out there, but what if your brain is simply an antenna for your consciousness to come through from wherever. Has anyone actually tried to boot up an artificial brain derived from a real organism? I'd like to see a proof of concept that your brain IS indeed the seat of your consciousness, and not just a fancy quantum antenna.
The concept of "multiple realizability" says that a brain/consciousness/mental state can arise from non-biological matter, like digital computers.
Modern proponents of this view do not view the brain as a seat of consciousness. To them, the view of a singular consciousness that houses in the brain like a theatre, is like a Descartesian illusion. Consciousness is distributed and all parts of "you" and your environment contribute.
As for "out there": I am always a bit worried when archeologists unearth some treasures with our current state of technology. Likely, in a 100 years they will have much better methods to research and preserve unearthed treasure, and so we may be spoiling their more effective methods by digging it up and putting it on display. What if, after the 8th great AI hype, another YC company claims it has found successful methods to upload your consciousness, which is 100% fatal to your preserved brain in the process? You'll be stuck in the MVP FORTRAN digital world of uploaded consciousnesses.
Or maybe they take our current infatuation with AGI to mean permission to create a huge ensemble of preserved brains, filling an entire room like did our 1960s computers, because it turned out that consciousness is only transferable to biological "organisms", and the only way to superhuman intelligence is to combine 20 human intelligences. The AI hype bubble will become a literal fulfilling prophecy.
I personally would either jail these consciousnesses (honor their will, but put them in a boring digital world with Archive.org access to the internet) or put them on display, much like we do with preserved Egyptian Pharaoh's. I'd call it Earth, and make Trump a president.
