Legally, yes.
> moment to moment
Some need twenty years to life.
My undergrad was in biochem. I have a decent grasp of how complicated biological systems are. I don't even begin to profess to have adequate understanding. I am not a domain expert.
That said, I don't see how imagining an engineering solution where measurements are taken of a brain's "state" and replicated with an algorithm are metaphysical psuedoscience. It's out of the reach of today's tech for sure, but I'd like to think we'll eventually make progress and one day be interested in solving this problem. Evolution stumbled upon human brains as a solution for propagation. We're all a lot smarter as hill climbing agents than our genes.
I do not think we'll solve this in our lifetimes, but it's so much better to think of than optimizing ad tech, election fraud, and structural inequality.
> philosophically rigorous work
You lost me here. I don't think something has to be philosophically grounded to be identified as a problem space and tackled. Epistemology ontology whatevers don't fuel rockets.
I'm not sure what consciousness is. I think of it as a transient emergent configuration of neural systems, like waves in an ocean, but I could be wrong.
Are you sure the you that wakes up in the morning is the same you that went to bed? Are you even the same person, moment to moment?
Weights change. Membrane polarizations are in flux. Microtubules, just one component in a deep sea of biochemical complexity, are dynamical.
> The true immortality
These are just words.
Evolution found genes as a solution. That's what your kids are. Humans have done even more with recorded words. I'd like to think that one day we can do the same with thoughts and minds themselves.
I like to imagine a future where you could download part of my mind and experience it yourself.
