Transhumanism also makes the elementary mistake of all sci-fi: failing to understand basic principles. Human consciousness is partial, highly fallible, and switches focus from moment to moment. It's totally reliant on continuous input from our sense organs. The idea of uploading something we know practically nothing about, yet do know is utterly connected to our sensory apparatus, is a priori absurd. Add to this the fact we haven't the slightest idea how to accomplish such a thing, and one instantly sees the utter silliness of transhumanism. It's no different from imagining we should all be racing around in flying cars with 1950s tail-fins.
