The Importance of the Constructor Theory in Physics

I think in mathematics it's unusual to run into a brick wall like that. We can choose which mathematical objects we think are interesting and worth trying to understand. But we can be mistaken and we can follow dead ends. By the way, I think that running into a dead end and making large mistakes unless they kill you, it's not all bad. In fact, it can be just as good as successfully discovering things, which the latter can leave you feeling empty. Whereas as Poppa says, if you're engaged with problems, even if you never solved them, then you're still having fun.
