I’ve got a few normal memories that aren’t bad in the slightest that make my brain sometimes feel “fuzzy” like a “I want to scratch it” kinda feeling, if you know what I mean. Not a literal I wanna scratch it. So, probably get rid of those memories first.

Then use the power to help others or get rid of some nuisances.

Younger people¹ playing loud music on the bus without headphones or using speaker phone will temporarily freak out because they have for gotten where they last had their wallet before getting on the bus. Even if they use a digital bus pass, they’ll still freak out because a wallet is your life.

No wallet? Then forget the memory of where they are headed. Not my fault you want to be a nuisance. Have fun trying to figure out where you’re going.

Being blatantly and proudly racist? I will take away all memories of you being that way, alongside any memory of racist rhetoric you have. Same with sexism too. Erase their identities so maybe, just maybe, they can learn to be better people.

Are you not part of a television show crew ( like that show about 3 friends in New York, I think, doing dumb prank like things ) and filming yourself committing a crime and/or being a real nuisance to everyone around you? Congratulations! You’ve lost your memory of how a smart phone works! Have fun learning that for the first time, a second time!

Also, if it’s for social media and I can see/recognize which social media it is, I will erase your memory of your account password, username, any recovery options, 2fa, ectetera, as well and help you by being a kind person and helping figure out how to use your phone, only to log you out of your account if you’re dumb enough to hand me your phone.

Real helpful stuff to make sure nuisances have a harder time.

Based on the other comments, I wonder…

If we could re-read, re-watch, or re-play our favorite media over again for the “first time”, we might consume significantly less media.

Why try something new that statistically isn’t likely to be the GOAT when you can guarantee an awesome experience with something you know, because you already know it’s great?

I can imagine someone who only replays one game repeatedly for decades, only watches one or two movies over and over, only reads one book or series again and again, decade after decade.

I already have that ability. Unfortunately I don’t have any control over it and stuff gets deleted without my knowledge

Look at the US Republican Party. Pretending history didn’t happen is basically the party’s platform.

Delete the memory of being able to delete memories, what happens now?

Forget my favourite books and read them again.

There is some horrible shit in my past that I’d definately get rid of. But, besides that gloomy sentiment, I’d use it to experience my favorite movies, games, and books for the first time again. Like seeing Whiterun for the first time or seeing the citadel for the first time.

Can I have the reverse and selectively recall memories my AuADHD/limited working memory forget?

I don’t think I’d personally have much use for it, at least so far.

But I see it going dark places. If people figured out how to delete their own, that’s one step away from authorities or even just criminals being able to rewrite other people’s realities.

I’ve been doing this unselectively over the past twenty years.
