I think I began as a rationalist when I read this story. (This was before I had run across anything Eliezer wrote.) I had rationalist tendencies before that, but I wasn't really trying very hard to be rational. Back then my "pet causes" (as I call them now) included things like trying to make all the software transparent and free. These were pet causes simply because I was interested in computers. But here, I had found something that was sufficiently terrible and sufficiently potentially preventable that it utterly dwarfed my pet causes.

I learned a simple lesson: If you really want the things you really want, then you need to think carefully about what those things are and how to accomplish them.
