Nobody that talks about uploading yourself has any idea what that means specifically. What's going on there? There's presumably some kind of machine that captures the state of every cell in your brain and how all the neurons are connected and accounts for hormonal influences and the range signals different types of neurons can make and so on. AND assumes that You are nothing more than what's in your brain. It's as though (somehow) ALL of you can be digitized and then reproduced in a virtual world while you're still a conscious entity that experiences genuine pleasure in your existence. You are so much more than the conscious thoughts floating around in your brain (which we're still a long way from really understanding biologically). You're an animal with hormones and animal instincts. All of your high level language is just an abstraction of the physical world in which all your ancestors human and otherwise evolved in for billions of years. You need that physical world obviously more than you know. There's nothing else you can understand, even in your dreams. The depth of physical sensations such as taste, sexual pleasure, physical closeness have a far more deep rooted place in you than anything specifically human. Feeling the breeze and the Sun on your face while taking a walk with a close companion may be something that can be simulated by something. But without a real loss? Making a machine that fools everybody and passes the Turing test with flying colors does NOT make it truly conscious. It just means humans are gullible. Look at all the people that inject intelligence into chatGPT which is fucking silly.
