Thinking deeply isn't about increasing complexity. It's about breaking problems down to their most basic form.
Evan Williams, one of Twitter's co-founders, gives his secret to building a billion-dollar internet company: "Take a human desire, preferably one that has been around for a really long time. Identify that desire and use modern technology to take out steps."
The desires that Williams describes aren't about summoning a car or a side of fries with a tap on your phone. They're more basic and immutable: getting from point A to point B, or just eating food. We want what we've always wanted. What technology allows us to do is get it faster, and without having to think about it.
The best ideas come from deeply thinking about how to make things easier for other people, and help them accomplish their goals with the minimum amount of effort. You might get there with tech, but that's also the part you should think about last
