Will humans or its technology reach immortality?
I don't think so. There's too many external factors that suggest it'll never be reached, but this person I'm having an argument with keeps suggesting that humans will become smarter and smarter (I don't deny this part) and wil built AI that will built smarter AI and so on. He thinks we can live forever or at least our technology can. I seriously doubt this. Humans will be more intelligent with much better technology in the distant futre, but our species will have its limits. We'll never reach a level where we'll live forever (and outlast the death of the universe at that) or to a stage where we'll colonized distant galaxies.
Any comments / thoughts?
