Quote:<br>
Uploading minds to computers isn’t just technically impossible—the<br>
whole idea rests on a deep misconception of consciousness and our<br>
place in reality. So argues William Egginton, whose recent book<br>
explores the relationships between the philosophies of Kant,<br>
Heisenberg and Borges. Drawing a parallel between minds and spacetime<br>
singularities inside black holes, he argues that to try to know such<br>
things involves trying to go beyond mere appearances to reality as it<br>
is in itself—a futile project, he claims. And if minds cannot be truly<br>
known, they certainly can’t be copied or uploaded to computers.<br>
Futurists like Ray Kurzweil and Dmitry Itskov, who aim for cybernetic<br>
immortality, are chasing a metaphysical mirage.<br>

<br>
Quite a long article.<br>
His main point seems to be that minds are not just data. If you don't<br>
fully understand how consciousness arises in the first place, copying<br>
it is impossible.<br>
OK, so we need to understand consciousness better.<br>
Let's hope that is not an impossible task.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">I haven't read the article, but just going off your description of it, it seems unsound to say both: "we don't know what consciousness is," and at the same time say, "we know it's impossible to upload consciousness."</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">Contray to my his claim, I would say we already have good logical reasons as well as empirical evidence to presume mind uploading is possible.</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">From: <a href="https://loc.closertotruth.com/theory/resch-s-platonic-functionalism">https://loc.closertotruth.com/theory/resch-s-platonic-functionalism</a></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">"When it comes to deciding whether functionalism is true, he says, we're faced with the following four propositions.</div><div dir="auto"><br></div><div dir="auto">1.

We thereby conclude that an emulation of a human brain would not only be conscious but must be conscious in the exact same way as a functionally equivalent biological brain. Thus, Resch concludes, functional organization fully defines the character of both consciousness and qualia."</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">Jason </div></div>
