How would the world and society be different if all humans had wings (like angels)? How would your life be different if you were the only one with wings?
I should have clarified - I really like outlandish science hypotheticals. As such, I interpreted your question as a science hypothetical. I also recruited yayfulness to help because he understands a lot about geography and urban design.
To figure out how the world and society would be different if humans had wings like angels, I decided I needed to understand the aerodynamics of angel wings. To my credit, I did suspect that angel wings would not work very well if implemented in reality. But I don't have a great understanding of aerodynamics, so I used google and found that thankfully other people tackled this for me here and here.
Basically, angel wings as depicted in most art would be useless. If humans with literal angel wings jumped off a cliff and tried to fly, they would die. Many anatomical changes would need to be made in order for flight to be possible. Among other anatomical tweaks (i.e., hollow bones, stronger sternum, REMOVAL OF ARMS), winged humans would need a 30 foot plus wingspan, which would result in difficulty folding the wings to walk around, so they'd drag on the ground. They'd also be really heavy. Very inconvenient, especially as the human wouldn't have arms.
There would also be significant metabolic problems. The energy cost of flying would be enormous. I can't quite figure it out exactly because I don't know how to factor everything in (and I'm not sure I would know to factor everything in), but humans would need to eat somewhere between 12,000 and 90,000 calories a day, or between 6 and 45 times as many calories as most humans eat roughly on average. And I'm not sure if that amount takes into account the loss of heat due to the increased surface area of the wings. There would definitely be increased competition for food, so it might make for a more violent society overall.
So, at this point, I can answer this question about how my life would be different if I was the only one with wings. First of all, if I was born with wings I assume they would have been surgically removed shortly after my birth. I imagine doctors would have seen them as undesirable growths. But let's say, so we can take this question as far as possible, that my wings were not removed. If the wings were functional, it would mean that I would have no arms. This would impact my life significantly. Once I learned how to fly I would have become very famous. However, at places like school, I'd probably get made fun of for being different and because my wings would drag on the ground. I probably would have avoided school, which would have been easy because I could fly and I assume the police would eventually get sick of dispatching helicopters, especially if I was not getting injured. I probably never would have even read the 100 Hour Board because it would have been more difficult to go on the internet.
I'd need to eat a lot of food which would have placed a financial burden on my family growing up, and would be even more expensive for me as an adult. So I'd need a really good job. I think I would probably start a courier company or became a specialized postal worker. Maybe I would also do shows to demonstrate my abilities to the public. I would probably need to work a lot of hours in order to feed myself, especially if I ended up needing something like 80,000 calories a day. Maybe I would join a sports team. Maybe I'd play professional basketball, I'd probably be really good at that because at the very least I could block all of the opposing team's shots. If I could make a decent salary that way so I could survive.
Yayfulness had many more ideas about how the world and society would be different if humans had wings, assuming that they have arms. He said:
