When I read Harry Potter as a child, I would feel a sort of melancholy when I finished the book and had to go back to a reality without magic. But as the years went by, I started to realize how much our world was starting to look like the magical world... it really is true that sufficiently advanced technology is indistinguishable from magic.

Moving pictures in the newspaper? We have iPhones and tablets and tiny screens with interactive video...

Talking to people through the fireplace? We have video calls on our phones.

Writing words into a diary and having it write back to you? Well now we've got that too.

Now I'm just waiting for the flying broomsticks. Maybe we can do something with magnets inside an electrified metal Quidditch arena...
