The World’s Biggest Problems

These rankings (below) are a compilation of my favorite world-changing problems.

  • I currently have 16 big problems to solve, ranked in my order of highest expected positive impact if they were solved.
    • I also have ideas for 84 potential solutions, three of which I’ve created into startups.

This project is inspired by one of my favorite quotes:

“You have to keep a dozen of your favorite problems constantly present in your mind, although by and large they will lay in a dormant state. Every time you hear or read a new trick or a new result, test it against each of your twelve problems to see whether it helps. Every once in a while there will be a hit, and people will say, ‘How did he do it? He must be a genius!”

— Richard Feynman (via Gian-Carlo Rota, Indiscrete Thoughts)

I’m also inspired by my version of the Hamming Questions:

  1. “What are the world’s biggest problems?”
  2. “Why aren’t you working on them?

There are way too many important problems in the world for any one person to solve, which is why I’m sharing them all here so we can get more people organized around all of these problems.

As I refine these ideas, I’m pushing myself to work in public and document more of my thought processes. I have started to publish my notes on potential solutions and will link these notes here once they’re live.

So my two ultimate goals for this project are:

  1. Start a constructive debate about the world’s biggest problems and best solutions.
  2. Convince everyone to work on the biggest possible ideas.

Let’s riff and refine on this list – share your big ideas on Twitter and tag me @neilthanedar for a response!
