I’m assuming these copies would also need to eat, sleep, and bathe as well, so there’d be some cost increases as these copies are added into the mix. Just getting extra jobs probably would only go so far before questions started getting asked or somebody noticed, so an army of me working multiple jobs really wouldn’t go well. I’d probably keep it minimal with only one copy, maybe two if I could make it work financially and set up some sort of work rotation so that “I” was only going into work once every few weeks. I might start doing a bunch of freelance design, writing books, gaming and whatever else.
Even better though would be if these were short-term copies that I could just absorb back into myself after a day or whatever and I didn’t have to worry about maintaining their bodies, like Mr. Meeseeks and they just disappear after their task is done. Then I’d just make copies left and right. “Oh shit, I’m out of milk. Copy #3,945,612, go get some milk, thanks.”
