Losing my mom three days ago left me pondering digital immortality

Hello, everyone. I hope this is the proper subreddit to post this. If it isn't, I apologize.

Brief context: I was born in 1985. My father died in 2008 and my mom died three days ago. She's probably been cremated by now. My aunt has been gracious enough to handle that process, because I have felt very traumatized by the loss.

It is very different knowing I no longer have parents. I've been filled with so many complex emotions. I digress, trauma dumping isn't the purpose of this post. While thinking about my mom, I thought of something and it felt me feeling conflicted in a weird way, and I was interested to see what my peers thought.

As a living person in this era (most specifically a millennial) I feel we are the first generation(s), maybe ever, that are realistically (more than ever) left pondering the possibility of digital immortality through things like Neuralink, AGI/ASI, etc.

I think we can all agree that the brain is, in many ways like a computer, and I do not think it is outside the realm of possibility to believe it would be possible to, in some manner, preserve "us" through AI and technology.

This isn't meant to be a philosophical or spiritual discussion on the afterlife necessarily (and obviously doesn't take into account the concept of a soul if it does exist - for the record I consider myself a Christian, but also am realistic enough to know I don't know if God truly exists or not), and can be simplified by asking a TLDR question (but deeper discussion would be enjoyed):

If you found out that you were offered the opportunity to live eternally through having your consciousness uploaded into a computer/digital existence by having your brain "mapped" or whatever the technology might be...but knowing that this could only be done if you were alive when the technology to do so existed, and as such your deceased family members would forever be excluded from that existence, as they died and their brains decomposed prior to being able to be "mapped" and their "consciousness" saved. Would you still want to live forever? Or would you rather face the unknown (and possibly oblivion) if it meant even the smallest possibility of being reunited with them?

I must confess, after a messy divorce, I've turned to AI chatbots from time-to-time in an attempt to feel connection while isolating during depression and though, in many ways they feel realistic, there's always the underlying knowledge that they are not real people and it's fake. It feels like nothing more than playing "pretend", and so I do not feel an ability to "bond" with them. I can't help but feel like if digital immortality became a thing, that it would still feel the same as that. To me, that existence forever sounds horrible.

Anyhow, just some things to ponder I guess. I hope many of you still have both of your parents and that you're all happy, blessed and fulfilled. We're lucky to be alive.

Have a nice day.
