This literally happened to me, only I lost way more than half my income.
It’s horrible, and frequently remembering the life I had is very painful.
I can’t work out what possible upside you think there is to this situation.
I don’t have any income at the moment so I’d take this deal.
But only because I’m curious what a life of leisure with the exact same material conditions would look like, as alternate me wouldn’t be benefiting any more than actual me would be losing out.
Oh god no. Not for any amount of money. What a total mindfuck that would be. Any person you meet, you wouldn’t be able to tell if you met them before or if your memory twin did.
You would constantly be questioning everything you see and hear.
Small things would drive you crazy. You distinctly remember going to the grocery store yesterday, so why is the fridge empty again. You swear you washed your clothes yesterday, yet everything is dirty. You remember hearing the doorbell, but no one is there.
Bigger things would make everyone else think you are crazy.
Your best friend who you hang out with every weekend? Nope, your memory twins best friend. Just a casual acquaintance in this reality. And they get more weirded out every time you tell them you had a great time last friday.
You are talking to your wife of 20 years only to realize its not your wife, its your memory twins wife, this version of her doesn’t know who you are, and she is panicingly trying to find her mace. The children you love, care for, and have watched grow up doesn’t exist in this reality.
Then there is the repeated heartbreak when those people that are the same in both realities diverge in terrifying ways. You remember visiting your mother yesterday, talking to her, telling her you love her, hugging her goodbye. You also remember her dying 10 years ago and know you’ll never see her again, except for in memories that keep coming that are not real.
Eventually you would just give up, accepting that you can’t keep remebering two lives at once. So you withdraw from society. Lock yourself in a room and slowly wither away as you remember a better life happening right now.
Undoubtedly worse.
I would rather spend half my money to let my kid have experiences that they tell me about excitedly at dinner every night.
