‘Mind Uploading’ & Digital Immortality May Be Reality By 2030 : Dr. Michio Kaku

There are two major questions surrounding the concept of mind uploading. There is the question of feasibility: Can we build a model of a brain complete enough to allow a conscious mind to emerge? The other question is concerned with identity. Some people argue that, if a copy of a conscious mind is identical by all measures (ignoring the fact that one is biological and the other is neuromorphic software/hardware) it should be thought of as a continuation of the mind that was mapped and uploaded. Others argue that a copy cannot be considered the same as the original, so the newly awakened consciousness must be another person.

Various attempts have been made to imagine the benefits of mind uploading. Assuming continuation of the mind, these benefits include indefinite lifespans and upgrading the mind. When your current brain no longer works well enough or not at all, you transfer your conscious mind to another (perhaps better) artificial brain. None of these benefits are tempting to those who see uploads as different people. In The Spike, Damien Broderick declared “copies are not you” and asked, “Would you be prepared to die (sacrifice your current embodiment) in order that an exact copy of yourself be reconstructed elsewhere, or on a different substrate?” He goes on to argue that this is not a procedure he would be willing to undertake. Let’s assume Broderick is right and a copy is indeed “not you.” Does it then follow that mind uploading offers no benefits?
