The clones retain the same physical attributes and memory as the original ‘you’ just before the replacement. From the clone’s perspective, it would be as if you swapped places with another person with no context of the situation that person was in, except it’s with every living person on earth, everyone but you cease to exist and the original ‘you’ isn’t affected in any way.
How would you imagine the world to become after this? How would the society act now that it has become entirely composed of 'you’s? How would you and your clones live the rest of your lives in such a world?
I’m incredibly scrappy, so we would get by. I can farm, I can repair stuff, I have a good work ethic, and I get along well with myself.
In certain sciences, we’re just fucked, though. I guess we just don’t do some of that anymore.
Edit: Also, probably about 80% of the world’s computer resources are now serving massive collaborative Luanti build servers. I’m not proud of this, but it’s definitely what the collective mass of my selves would do with all of our free time.
Edit 2: I guess we also probably implement a worldwide tax on all income by all copies of me, to pay a few hundred copies of me to contribute to the Luanti project full time.
