"Cool, but the muggles are in space. They've colonized planets and mastered aspects of the universe we didn't even consider. They've spread out into the stars, advancing human knowledge in leaps and bounds. The other day I saw an old muggle die on the street and then be brought back to life within minutes. No catches, costs, or curses. He was dead and then he was well again. What are WE doing?"
When you consider how ridiculously OP magic in the HP universe is the wizards could already do those things if they wanted to: attach a portkey to a broom and enchant it so it flies out the atmosphere to Mars or whatever, then use the magic spell that creates an air bubble around your head and warp to it.
And wizards can extend their lives with unicorn blood, which they would set up farms for if they weren't retarded (they also have magic that can fix pretty much any physical injury, and they can change their physical appearance easily, too).
Wizards can also duplicate any object as many times as they want, so they could cure world hunger (and any other kind of problem caused by not having enough of any non-magical object).
They can also create sentient paintings that can think for themselves and have memories, which makes them superior to any muggle computer AI.
A group of schoolchildren manage to create a map that automatically names and tracks all people within a given area, so presumably even more expansive versions should be easily possible by experienced wizards (which would be far more advanced than even GPS microchips in terms of how it would allow you to track people).
Hermione manages to create magical coins that instantly react to a predetermined condition, changing their form - which means that instantaneous passing of information is possible (and building computers using magical objects that change state would also be possible).
Broomsticks don't require fuel (nor does any other kind of magic, including apparition which is just teleportation). Portkeys don't either. Wizards can travel anywhere instantly for no money or expenditure of resources.
There is literally a "luck" potion that you can drink that makes everything around you work in your favour.
Literal fucking time travel is possible and so mundane that children are trusted with it.
Rowling didn't restrict her magical system enough and it makes wizarding society look inept in how little they've achieved with such incredible abilities.
And it creates a ton of plotholes in the stories: why were the Gaunts so poor when they could easily duplicate food and cloth and anything else? Why didn't either side of the wizarding war use time travel? Why not create immortal versions of anyone you like by just making a magical image of them? How could a wizarding economy work when you can duplicate most objects and render their monetary value as nothing? Why are there not a bunch of kids dying every single day at Hogwarts given the incredible dangerous magic they have access to and how relaxed supervision is?
