The Pit

If I had to say (and this is only a slice of the story), I am the boy and the scientists (or whatever they are) are the rationality community. Rationality showed me light, taught me how to seek truth, saved me from destructive biases. Many others in my position dropped their "conventional" lives and moved to Berkeley/started working on EA or AI Risk. But me - after my interaction with rationality - I turned away from the community to continue grad school and pursue my pure mathematics with renewed vigor.

[Hammertime Final Exam] Quantum Walk, Oracles and Sunk Meaning

I just stumbled back into LessWrong after many months, very pleased to see that you completed this journey with such seriousness! Looking forward to your thoughts and comments in the postmortem post.

Re: Sunk Meaning, immediately after reading this, my brain sent strong signals that *something else is going on here* with regards to making the cow's death mean something and there's some Chesterton's fence that you shouldn't break. I think the error you're making is basically the same error that causal decision theorists make two-boxing in Newcomb's problem. You do not get to choose whether or not to honor a dead cow in this specific instance. You only get to choose (for all time) whether or not your source code implements an algorithm which honors the dead. Being able to do this is really really useful for all sorts of Newcomblike situations that occur in real life.

[Hammertime Final Exam] Accommodate Yourself; Kindness Is An Epistemic Virtue; Privileging the Future

I identify strongly with the "Accommodate Yourself" - a substantial fraction of things I figured out with rationality boiled down to realizations of the form "You didn't have to live like this!" I set up a Schelling point for my glasses so I didn't have to scramble around looking for them every morning. I got over the inherent virtuousness of cooking my own meals and tried Mealsquares. I got a monitor and mouse for my laptop. The list goes on...

Kierkegaard wrote "So only one lack remains [in our time], even though not yet felt, the lack of difficulty. Out of love of humankind, out of despair over my awkward predicament of having achieved nothing and of being unable to make anything easier than it had already been made, out of genuine interest in those who make everything easy, I comprehended that it was my task: to make difficulties everywhere." It seems to me, however, that despite all our progress, life is sufficiently hard as it is. We don't need to make it any harder than it has to be.

With regards to the thoughts on delayed gratifications, it seems like a valuable reminder that pendulums usually swing a little too far in the other direction. Most people most of the time would benefit from a reminder that the future exists, but some smaller fraction of them also need the reminder that the present exists too.

Thanks for following Hammertime, and I'd love to see more of your writing on here in the future. =)

Unyielding Yoda Timers: Taking the Hammertime Final Exam

I like (2) a lot, I find writing up talk/lecture notes on a topic extremely productive. It's surprising how many details I'm always missing that take work to produce.

Would you mind commenting a link to this on the original final exam post?
