Granted, but it turns out to be too expensive to be practical.

I wish for an end to the use of fossil fuels for power, but that this be done without reducing the amount or distribution of power available.

Granted, now there's a nuclear plant for every small town and even the efficiency innovations of the past 30 years mean each plant still produces 1 barrol of waste per-year.

I wish arthropods never existed.

Granted, but crab meat and crab eggs are so delicious, so mother nature creates crabs, lobsters, shrimps, etc.

I wish I could burn calories while doing nothing, being sedentary for long periods, instead of getting chubby.

Granted. You now burn calories so fast that you start going hungry. You eat some food to try to stave off the the hunger, but that doesn't help, and you end up starving to death *while* you are eating.

I wish for a computer that is fast enough to compile even major software projects, like chromium and libreoffice, in under a second.

Granted, but it needs its own power station.

Wish the James Webb telescope works flawlessly.

A little too flawlessly, perhaps. It spots the massive black hole heading directly for our solar system.

I wish I could go back in time and advise my childhood self.

Granted, but you advise your childhood self to, on reaching your current age, not go back in time to advise your childhood self.

You, in turn, follow that advice, creating a time paradox.

I wish for a new computer monitor that has integrated speakers and at least one HDMI input.

(I am actually seriously looking at getting such a thing, but this is not the place for serious discussion of that.)

Granted, but it has a hidden mic+cam connected to <insert name of chinese company here>.

Wish flat-earthers had to wear a big pointy DUNCE hat in public.

Granted, but then such dunce hats become the "in" thing in fashion and everybody starts wearing them.

I wish anti-maskers had to wear a mask that said "I AM AN ANTI-MASKER" (in all caps) in public.

Well, okay; but once the world begins to adopt some Japanese cultural norms, we decide to go all in. Including, but not limited to: overly cute mascots for everything, non-winter-friendly school uniforms, fermented soybeans for breakfast, and pachinko parlors everywhere.

I wish I could speak fluent Japanese, without forgetting my English.

Granted, you keep all your English but forget your toilet training.

I wish for all the powers of a Q but none of the responsibilities or liabilities.

The letter Q has no powers, so your wish does nothing.

I wish that everyone could control the weather at will.

Granted, but within a year the global climate is wrecked resulting in mass extinctions.

Wish I knew how GOG game gifting worked, so I could consider gifting.

Granted, you see a store-page for a game you already have and notice the purchase button has been replaced with "purchase as a gift" (there's also a box to check if you want to gift a purchase before or instead of getting it for yourself) you so dumb that you reject all of technology and become a hermit.

I wish every lost or unwanted Lego in the world would teleport into my collection.
