Depending on the solution, normal dying might indeed be impossible. I remember a piece of dystopian fiction (I think it was an Outer Limits episode) where characters couldn't even kill themselves anymore because nanobots would instantly repair any damage.

Not that this scenario is extremely likely but there might be ramifications we can't think about yet. Immortality after all isn't a particularly well-trodden path.

Black Mirror's "White Christmas" covered a similar theme with uploaded consciousness, where the victim obviously couldn't self-terminate in any way.
