&gt; The beliefs I have would not be immitateable by such methods, even if brain uploading is achieved.<p>Feel free to skip it, then, but many others want the option.<p>&gt; It could not properly deal with the problem of my moral imperfection.<p>Morals depend on the ability to empathize, evaluate the effects of your actions on others, and act accordingly.  So, you can indeed give yourself the tools to become far more moral.<p>&gt; Also, a computer would have only finitely many states, so it would only delay death, not prevent it, as having the same exact mental state an infinite number of times would, I think, be indistinguishable from having it only once.<p>There&#x27;s a huge amount of theory on how fun and novelty work with enhanced cognitive ability, with many potential solutions to that problem.<p>Beyond that, <i>long</i> before we deal with the finite number of interesting mental states, we&#x27;ll have to deal with the heat death of the universe.  Given a few billion years to work on both problems, I think we&#x27;ll manage a solution.  I&#x27;m far more concerned about whether we can solve mortality before the next existential threat to humanity than about whether we can solve problems like the heat death of the universe in billions of years.
