One issue i see here is people saying "But would it still be
you?"
I'm not sure how that could be answered, but even if it's not the same as you is that terrible?
Now, yes, getting hacked to be a good l'il corporate servant sucks infinite ass, no argument there.
But as to remaining 'you', are you the same you that existed when you were 10? Are you the same you that you were 20 years ago? Have you changed thru education, growth or some sort of trauma? Trying to remain the same you you were long ago means you didn't become more than you were.
In 'ghost in the shell" (Not the whitewash live action mess) Motoko Kusanagi is offered a chance to merge with a fully sentient self aware AI that evolved in the internet's sea of information. She asks how she can be sure she'd still be her.
Project 2501 admits she can't be sure she'd still be the same, and says you cannot become what you could be by remaining what you are. Your effort to remain as you are limits you.
So maybe a you that became a transhuman ego able to shift from body to body, fork and reintegrate, etc wouldn't be you as you are now. Would it be better? Worse?
Honestly arguing if humans would be the same after transhuman tech, mind uploading, morphing, etc opens a question: "Is humanity so good it shouldn't change?"
Yeah, i'm glad we changed from our ancestors who practiced open slavery, total dominance of women, human sacrifice, etc. You look at the well documented and recorded 20th century and i think you see that the human race as it is now needs some improving.
Look, america today would shock the founding fathers, i mean they voted for slavery, declared a black man was property and amounted to 3/5 of a person, woman could not vote, etc. in most of america a woman could not have her own bank account until the 1970's. Imagine them seeing barack obama sworn in as president.
Society, culture and the people in them change, and i for one am glad we do.
Sure change can be bad, it can be good. But stagnation is bad, period. The hypercorps show some people and things have not changed. The Argonauts and the Titanians show some things have changed.
So, yes, people will be changed by technology and new abilities, all we can do is try the best we can to make it positive change.
