This, I suppose, is the future. Children who know nothing about design, nothing about machines, can build the toys of their dreams out of nothing. And that's just the start; It only gets more exciting from here.
My kid, like half the other girls at her school, wanted to be Hermione Granger—queen nerd of the Harry Potter world—for Halloween this year. In the past, this would have meant a lot of work to pull off. A lot of thrift store shopping, a lot of handsewing, a lot of approximations of Gryffindor colors, crests, and details.
But this is the future, so every part was easily available on Amazon. I bought the whole outfit from crested robes to official Gryffindor tie in 30 seconds on my phone while waiting in line at the grocery store. Which is exactly how the future is supposed to work, I think.
