My wife and I bought one of the Nectome pre-sale discount cards. This is the second five figure purchase I have made based pretty much entirely on a highly-upvoted LessWrong post.
I've also lost 20 lbs in the last year and have more energy than ever (despite having a newborn at home) by injecting myself with research chemicals that I heard about on LW, and have taken investment advice from people here that has paid for everything above and more.
Our polygenically-screened kid is 3 months old. I am ambivalent about the term superbabies in general, but he is definitely "super" to us already, whatever the effect of applying a little extra selection pressure on his genes turns out to be.
The jury is still out on Nectome, though I think my fellow Max H (a different person!) makes a pretty good case for them, even (or perhaps especially) if you have short AI timelines.
More generally, while I am uncertain about playing to your outs as a strategy for averting AI doom (or just what it actually looks like concretely), I think a similar sort of idea works quite well as a strategy for living a good life in the face of it. Now that I have a dependent, I am signing up for life insurance and following other standard advice, as well as doing the things that I think should be standard practice for responsible parents, despite the fact that, on my own inside views, a lot of this stuff is pretty negative EV (more so than the normal way that insurance is always negative financial EV for the buyer).
I also derive enormous benefit from the original Sequences, and from actively participating in the discourse here these days: seeing interesting takes, sharpening my thoughts and ability to express them in writing, emotional stability, introspective ability, (well-calibrated) self-confidence, etc.
All this is to say, a heartfelt thank you to everyone here, especially the authors and commenters of all the posts linked above, as well as @habryka, the Lightcone team, and Eliezer for maki
