This is really interesting because the four-color theorem seems to sit right at the boundary between proving that something is true and understanding why it is true. The fact that mathematicians are still looking for cleaner ways to approach a theorem that was already proven decades ago says a lot about how important the structure behind a proof can be.
I also like that this new work isn't just about replacing computers with humans—it seems to be using the old problem to reveal something deeper about graphs. That's probably the more interesting result in the long run.
