Could this backfire? Like, sure, no combustion engines, but that would be solved in the long run with electricity. But are there things I'm forgetting that would be critical? Like a chemical process for critical chemicals that requires explosions or something like that.
Resource mining, large structure demolitions, SFX pyrotechnics for film, television, and stage. Exploratory and scientific rocketry, rescue flares, backup generators, trains, industrial diamonds like the ones on diamond-tipped tools.
Essentially what this guy wished for was a full arrest on rapid exothermic reactions which are used in many manufacturing processes, scientific experiments, and life. Hell, I just checked and technically the process that causes things to explode is roughly the same one used by our cells to process ATP into energy for the persistence of our life (and most other non-fungal and non-plant life).
I actually never said that. I said backfiring cars. You are changing my words to fit physics, instead of looking at a genie wish being magical. But okay, if we change my request to fit that all, not just loud and explosive dangerous explosions, but all explosions including the internal combustion cars don't work, then I guess we go electric engines.
But I figure I just meant what I said, I guess you are in charge of monkey paws?
The original Monkey Paw is a story where people get wishes while holding a mummified hand. It counts down remaining wishes with its fingers. But every wish gives the result asked for, but doesn't fulfil the spirit of the sish, just a literal truth and a nice large handful of bad luck to go with.
For example, you wish for millions if dollars. The finger folds.... And a loved one dies, leaving you with a massive insurance policy payout. You get the money but are massively bereaved and you are the killer!
These days a monkey paw is often thought of as someone who gives whilst taking away, but any granting of a wish while ruining the spirit of the idea qualifies. Like deciding I wasn't specific enough about my explosion damper, and taking out internal combustion cars, and even the sun, with the same hand as removing bombs.....
