The alternate version of you was kind enough to wish for someone else’s health and happiness, and wanted nothing for themself.
That’s why I specified “still me, with my goals, values, etc.” I KNOW myself and this wouldn’t happen.
What WOULD happen is “You get a machine you cannot understand. You spend days / weeks / years trying to get it to do SOMETHING, ANYTHING, but it never does. Then, one day, after wasting countless hours of your life, you get it to turn on and it immediately causes <terrible, life ruining disaster> before spinning out of control and tearing itself apart.”
Oh, you want your interpretation where they have your exact same desires? Granted. That alternative version made the exact same wish you did. It’s selfish all the way down, so there is no version where someone made a more concrete wish and you still get nothing.
You can’t have it both ways. You can’t have someone who is incredibly different but also exactly the same. It’s a contradiction.
Oh, and your curse isn’t what would happen. It’s just a bad fanfic plot device.
