There are niche scenarios where a horse is more useful(e.g. rough terrain), but for 99.9% of the scenarios of modern life, a car/motor is more powerful and reliable. Horses are also noisy(clop clop clop) and have been known to trample people.
Supersonic flight was tried with the Concorde and its profitability was iffy due to large subsidies involved in its development, and the handling of BA privatization in the late 80s. There are aerodynamic constraints that make supersonic flight inefficient. Unless we magically change physics, supersonic flight is always going to be significantly less efficient than subsonic flight.
Also the quickest way to make something that is starting to become viable(electric cars), less viable, is to make it have to fly(flying drones). You now have to fight gravity 24/7.
This isn't about dismissing the future, it's about people trying to implement these ideas for the last 70 years, and some spunky "disruptor" startup isn't going to magically change the laws of physics once we "git rid of that dang regulations!"
