It's weird since besides being a meme idea like "uploading your consciousness", I'm pretty sure the issues with the idea are a common thing in sci-fi. Even if you accept the theoretical, you're heading straight into "Ship of Theseus" territory and question at what point do you cease to exist in favor of....some homunculus as you keep discarding bits of your self. The absolute horror of existing as zeroes and ones that can easily be copied, discarded, or replaced.
Thankfully, these are fictional ideas.
