Jan 20, 2023 at 14:42 comment added DKNguyen Those are bad examples. Would you replace your legs with wheels? Cars are pretty useless without roads. Also, helicopters are really big for something that hovers. Look at how big hovering animals are compared to animals that can't hover: hummingbirds and insects. They guzzle fuel. You can't find that much food in nature to survive and even if you could you wouldn't be able to consume it fast enough. Hummingbirds drink sugar and barely eat fast enough to not starve to death. At the sizes flying animals exist at wings are more efficient.
