Buck's Shortform

Some chance it's outdated, but my advice as of 2017 was for people to do one of the top bootcamps as ranked by coursereport: 

I think most bootcamps that aren't a top bootcamp are a much worse experience based on a good amount of anecdotal evidence and some job placement data. I did Hack Reactor in 2016 (as of 2016, App Academy, Hack Reactor, and Full Stack Academy were the best ranked bootcamps, but I think a decent amount has changed since then).

An update in favor of trying to make tens of billions of dollars

I think $20B in 4y is somewhat of an outlier, even among super successful billionaire founders. Eg a few quick googles (assuming CEO has something like 10% of the company after several rounds of dilution)

  • Facebook founded 2004, 2008 valuation $15B, CEO $2B?
  • Airbnb founded 2008, 2012 valuation $2B, CEO $200M?
  • Uber founded 2009, 2013 valuation $3.5B, CEO $350M?
  • Stripe founded 2009, 2013 valuation $2B, CEO $200M?
  • Aurora founded 2017, 2021 valuation $13B, CEO has something like $4B
  • Tesla founded before Elon, but Elon CEO 2008, 2012 valuation $3.5B, CEO $400M?
  • I considered adding Google/Microsoft/Amazon/Apple to this list, but since valuations have increased a lot over time and they were started much earlier, they look less impressive, and it doesn’t feel quite fair.


  • perhaps there are many more quick crypto billionaires in particular, given how much crypto has increased over the last 4y
  • valuations have increased over time, and maybe people have examples of other tech founders of companies started closer to 2017 where the founders did better
  • several of the CEO’s on this list have gotten >$10B, it just took more like 10 years than 4
Early career EA's should consider joining fast-growing startups in emerging technologies

I agree that selection bias and survivorship bias affect things like this, and it probably would’ve been good to call those out explicitly. I have a draft part 2 of this post that discusses that and how hard it is to get a job at one of these companies.

I also appreciate the comment directed at people that might feel alienated by the post, and agree that I don’t want those people to feel alienated by this. A more positive frame on this post would be: some people think that they can only work at the ~10 EA orgs they think most highly of to have a good next step, and I think there are at least ~100 startups that they could also consider that would also be very promising. I think in general, it’s easier for an early career EA to get a job at a fast growing startup than one of the top EA orgs.

I disagree with the point about FAANG being a better option. I agree it’s a solid, lower variance option, but I think it’s higher expected value to try to get a job at a fast-growing startup for people that feel like they could do that.

But anyways, I’m sorry to anyone that felt alienated by this post, and I think not feeling like you can get this kind of job doesn’t mean that you can’t do lots of good things for the world.

Early career EA's should consider joining fast-growing startups in emerging technologies

I have a draft part 2: it’s easier than it sounds. One of the reasons I believe that is because many of the best-of-the-best startups have many vc’s that want to fund them (so it’s not as hard for them to identify which are the best, but it is hard for them to compete to be the one to fund it). On the other hand, these startups need all the excellent employees they can get.

Early career EA's should consider joining fast-growing startups in emerging technologies

Makes sense, upvoted. I like “fast-growing” more than “top,” because “top” makes me think more “is already Airbnb” vs “could be the next Airbnb.” Maybe the best term would be “exceptionally fast-growing” or “exceptionally likely to be successful.”

Fast and successful are definitely a spectrum, and it seems definitely true that somewhat successful is still good for career development. I think one claim I didn’t spell out fully is that people aren’t selective enough in choosing which startups to work at. Of friends who worked at companies in the “YC or Techstars startup” reference class, I think several had really positive experiences, but several worked at companies that went under and weren’t that positive, and it seems to make a big difference to choose one that is exceptionally good vs ok.

We're Redwood Research, we do applied alignment research, AMA

We're a nonprofit. We don't have plans to make profits, and it seems less likely than e.g. OpenAI that in the future we would go nonprofit --> tandem for-profit / nonprofit, but there are a variety of revenue-generating things I can imagine us doing (e.g. consulting with industry labs to help them align their models).

When to get a vaccine in the Bay Area as a young healthy person

(As of  ~4/1, I've seen a much higher anecdotal success rate w/ strategies like this)

When to get a vaccine in the Bay Area as a young healthy person

In hindsight, I would've liked to spend more time editing my original post  (I was trying to get it out quickly). I think the framing I would use in hindsight is:

I'm hugely in favor of young healthy people finding vaccines that are either 1) going to be thrown out, 2) at a place w/ extra time slots that wouldn't go to someone else, but 3) from the evidence I've seen, it seems like 1/2 aren't options right now, and so 4) trying to find a way to get a vaccine right now seems likely to be taking directly away from someone else who is higher risk. There are still other ways to justify this (e.g. catherio's comment about ethical offsetting), but because I've heard a bunch of rumors along the lines of "1/2 are options right now," I wanted to share that the evidence I've seen suggests that's largely false. It's probably also not a big deal if someone gets a vaccine early, as it seems likely people will be able to seek them out within the next ~month.

When to get a vaccine in the Bay Area as a young healthy person

I agree that slow rollout is more of a problem than poor prioritization.  But at least in the Bay Area, I think trying to get a vaccine as a young healthy person right now is in expectation directly taking away a vaccine from a more at-risk person  for x weeks, and haven't seen significant evidence against that yet. As soon as there is the ability to e.g. drive somewhere to get vaccinated where the time slot would have otherwise gone to waste, I'm strongly in favor of doing that.
