I was watching some "how was it built" shit and one of the things that I find interesting about such documentaries or actually the building processes themselves is the constant search for solutions. Like you got a problem you fix it, but that creates another problem so you fix that and so on and so on until the thing is "perfect".
So anyway, I was thinking couple of people could give short hypothetical solutions for the world's core problem (whatever you think that is) and then we can all built up on the theory until we fix all the possible problems. Before we get into the problem fixing we will vote for a winning theory and then the winner will expand on it as much as he/she can after which we will start looking for bugs and solutions.
What do you think?
