Well, you're making decisions about someone else's mortality. Maybe they wouldn't want to live forever with everyone else that they knew dying? Maybe they would want to have a physical existence in the form of a human body. You're denying them that.

There are a ton of similar questions.

I think the parent's phrase "sufficient technology" was meant to be interpreted as more than my "brain uploading and emulation"—i.e. an infinite Matrix landscape, synchronized with a doorway in the real world, that would gradually quantum-de-/re-materialize them as they progressed further into or out of it, so that, on the outside of the door, they were real people made of real matter, but ten or fifteen feet inside they were completely virtual. Assuming a wide-enough door, you could bring in your house, your car, whatever else you'd like, and bring them out again if you wanted to live a mortal life. (But, if you got your leg blown off in reality, you could always go in and, sufficiently digitized, apply a patch from a record of your previous body and walk back out, good as new.)

The problem with speculative fiction is that it needs a technological conflict. Worthwhile utopias don't do that.
