Kurweil says we will be immortal because the singularity (digital mind) is near .
No need for heavens you can upload your mind and store it digitally as soon as 2100.
Unless some one forgets to pay the electric bill...
...and even then, supposing the unlimited energy required to power such a digital mind storing machine for eternity to escape the need for a theoretical heaven...wouldn't that uploaded mind just be a copy...mightn't one still be rotting in the theoretical hell or whatever no matter the state of the copy?
