Well then, one of them can make this wish for this batch and the other can maybe do a future batch.

And how do the replacements fare?

At first it seems like it's just a straight-up replacement with no side effects.

But after enough time it'll become pretty obvious that they're getting noticeably less conflict-seeking.

Well, this side effect - or reversal thereof - can be warned for.

Most of the people who are against it are the sorts who you don't really want seeking more conflict than necessary anyway.

"Well, I don't normally base my willingness to alter people's emotional proclivities on how I'd rather they be but since this is plausibly the work of an alien parasite and if they keep using their powers zillions of people are forked only to promptly cease to exist I can relax that a bit."

In that case they will achieve a complete replacement of all simulation-based powers with similar magic-based ones.

There's still the matter of how the entities literally use those things to think.

"About that, you managed to talk to me and I can't be simulated. You must have something else going on."

"I have interacted with enough humans—simulated and otherwise—to be able to reliably mimic your speech patterns and communicate without needing to actually simulate anyone. It's a bit subtler than that, though—just like humans imagine possible situations in order to plan for them or respond to them, so do we, but with more detail."

"I can understand reluctance to try moving your entire brain substrate onto another format. Our magic precog without cape-style limitations is out of range of the wish machine, unfortunately."

"If you can make sure the functionality will remain the same, I do not object to the substrate change. I will have difficulty feeling as strongly about it as I do about matter creation, however."

"Someone else can make the wish, it just might take some time to find a candidate."

"I understand. ...would it be objectionable for me to simulate and instantiate a person who would in fact feel suitably strongly about this?"

"Yes."

"That's a shame. I can wait, I suppose. I will be able to communicate—reasonably—if constrained not to simulate anything complex enough to itself be sapient, so from your end it shouldn't be much of a problem."

"We'll look for potential wishers."

"Best of luck!"

"Thank you."

"...so...now we go and stop all the other ones?"

"It'd be a good idea to have these ones converted to magic first, for proof of concept and so they can consult. After that yep."

Bounce cling hug.

And eventually the substrate change is completed for the entities themselves, and they can consult.

The Warrior doesn't know the expression "never been happier" but if it did it would use it.
