In my thoughts, i've created a google chrome style browser with less than 300 lines of code. It involves some sort of AI and the language uses specify a lot.
… and if you could actually do that sort of stuff in the real world instead of in your thoughts, Google (and lots of other companies) would throw so much money at you that you could end all poverty and still have more money than you could ever spend.
If we're going to go all dreamy, I can think of a machine that looks like a really cool hat that you can wear, and makes every game idea you'll ever think of magically appear fully created with the best graphics and gameplay ever. You don't even have to type a single line of code. How can any other invention ever beat that for game development? It'll use some clever neuro-science or something, and you have to focus on your idea for 10 seconds.
There is a world of difference between "I've got this fantastical magical thought-concept for something - I'm sure it's going to be awesome" and "This is a fully-functioning realization of an idea".
The former is easy. Ideas are generally easy.
Execution is hard.
