I had an existential crisis a few weeks ago that was very helpful. I now fully believe "it's physics all the way down." It's also given me some insights as to how self-awareness arises in physical systems, and made me realize cryonics is trivially workable. I also have an intuitive feel for how humanity is collectively wearing rose-colored glasses, and am very curious what happens when these will get taken off! (In other words, I look forward to the creation of a fully rational agent according to a prescribed utility function.)

This also means I can hardly stand news and movies anymore, because I deconstruct everything. I have no problem maintaining social interactions, but no longer carry any of the standard social obligations. It's a little eerie, like feeling the matrix.
