If we ever learn how to digitize the entire species into hardware, leave our biological husks behind and become robots... Will god be pissed about that? Do we go to a robot hell? Do robots have a spirit to send to a robot hell?
God's original command to humanity is to go forth & multiply. In my opinion, AI is just as much our offspring as a human baby. I can't see why God would have a problem with us building intelligent machines.
As for a soul/spirit, if such things exists (as I obviously believe), I believe they are spiritual creations given to us by God. I don't believe a soul can be created by the growth of a biological brain, nor do I believe we could engineer a soul. In essence, if hunks of intelligent meat can have souls, there is no reason why hunks of intelligent silicon can't have them, too.
Now, as for downloading our consciousnesses into a machine body, I certainly hope that's not a sin because if the technology becomes available in my lifetime, you can bet that's exactly what I plan on doing!
As for yiffing in Hell, yiffing is horribly overrated irl. How could it possibly improve in Hell (assuming yiffing in Hell is even possible...)?
