I have a file of notes about essays I might write in the future. Typically I'll have about a paragraph about each. I was curious how long the file was. 1792 lines! In practice this file is practically write-only. When I have an idea for an essay but don't have time to write it (e.g. because I'm in the middle of another) I make a note of it in the file. But I pretty much never go back and read them.

Want to start a startup doing eye-tracking? If so I'd be interested in funding it. A friend of mine has ALS and can only move his eyes. He has an eye-controlled keyboard, but it's not very good. Can you make him a better one? The reason this is worth doing as a startup is that I think eye-tracking may turn out to have broader applications than it currently does. It may even be a component of the next form factor in computing, the nature of which is still strangely unclear.

When you talk to more established founders, there's a common theme: late-stage investors pull some nasty shit. Once you get past series B you should stop optimizing for investors who can help you and switch to optimizing for ones who won't knife you if things go bad. One reason late stage investors behave so badly is that they're not worried about reputational damage the way seed and series A investors are. But YC may be able to make them start to worry. YC keeps a list of who's done what. Eventually that will affect their deal flow.

When I'm trying to help founders find new startup ideas, I usually start by trying to figure out what's unusual about them. What do they know or care about that few other people do? There's usually something, and it often leads to an idea. If this new idea was already inside them, why hadn't it bubbled to the surface? Two reasons: they didn't realize what was unusual about them, and they discounted it as a source of ideas.

Talked to a programmer today who said AI coding tools made him about 10x more productive. Though 10 seems like a round number, this was an attempt at a precise estimate. If that kind of increase in productivity were the norm, it would make starting a startup qualitatively different, because you could do with 8 programmers what would have taken 80, and a company with 8 programmers is much easier to fund and run than one with 80.

Observation suggests that people are switching to using ChatGPT to write things for them with almost indecent haste. Most people hate to write as much as they hate math. Way more than admit it. Within a year the median piece of writing could be by AI. I warn you now, this is going to have unfortunate consequences, just as switching to living in suburbia and driving everywhere did. When you lose the ability to write, you also lose some of your ability to think.

Oklahoma plans to kill Richard Glossip on May 18. The state's own attorney general has said that this would be a "grave injustice," but other people in Oklahoma are determined to go ahead and kill him. Sound crazy? Keep reading; it gets crazier. Image How did this happen? The usual mix of sloppy police work and corrupt prosecutors determined to win at any cost. The Innocence Project estimates that about 4% of people on death row are innocent. Richard Glossip is one of them.

Electric cars, fake meat, AI. All three have been around since I was a kid. They were never good enough, so we learned to ignore them. But all three have now crossed the line where you can't. What's next? As these examples suggest, "What's been around for a long time, but has never been good enough to take seriously?" is a good heuristic for predicting important new developments. When people have been trying to do something for a long time, there's usually a reason.

Amazon is the biggest used bookshop in the world, in the sense that they pack books so badly that any book you buy from them will be a used book by the time you get it. When I want to buy a book that's still in print, I begin by looking for a used copy in good condition on ABEbooks, since I know a reputable used bookshop will at least pack it well. (Yes, I know ABE is owned by Amazon.)

The amount of equity you'll get in a startup decreases exponentially as your employee number increases. If you want to get rich from a startup, you have to be there early, either as a founder or an early employee. But here's something few people get: startups need different kinds of work early on than they do later. So your chances of getting rich from a startup vary enormously depending on the type of work you do.

The underlying story, both here and with that BBC interview, is that there is now a whole generation who (a) have little respect for journalists after being treated dishonestly by them, and (b) no longer fear them, now that they've lost their monopoly on the news. People who've grown up in this new world may think "Weren't things always this way?" No they were not. A generation ago, even the most powerful people used to try to stay on the right side of journalists. Very few dared to be openly contemptuous of them.

Jessica: What's new?

Me: OpenAI just released a new version that's much better. And people hadn't even stopped talking about the previous version yet.

Jessica: Are you scared about AI?

Me: A little. At the very least, it's going to change everything. One of my tests of the magnitude of a change is: How does it change what advice I'd give my kids? And when I try to answer that question, it's scary how little I can predict. The best I can do is tell them to surf this wave rather than be crushed by it.

When you're doing a deal with a large organization, find out if the people you're negotiating with actually have final say. Usually they don't, and that means the deal you've agreed upon can be, and often is, killed at the last minute by higher ups. Here's a simpler version that works just as well in practice: when making a deal with a large organization, no matter what they say, assume the deal will be cancelled at the last moment.

One of the things AI coding assistants are showing us is how much duplication there is in the code that's out there. Most people just write the same stuff over and over. Hypothesis: The more original your work, the less AI will help you.

Trends in mental health problems among US women and girls, 2001 to 2018. It's so obvious that something changed, and we all know what it is. Image This graph is from @Noahpinion's article on the subject. I agree that "It's the phones" should be our default hypothesis. Though it's not the phones per se; it's the apps.

One advantage of living in the UK is that, by imagining explaining them to a British person, you're able to see the true weirdness of things about America that you might otherwise start to take for granted. For example, that in America, following the advice of epidemiologists during an epidemic is considered a political statement.

One of the differences between the AI boom and previous tech booms is that AI is technically more difficult. That combined with VC funds' shift toward earlier stage investing with less analysis will mean that, for a while, money will be thrown at any AI startup. Since these investors won't understand the technology, the way they'll decide what counts as an AI startup will be based on the founders' credentials. This will be an odd, but temporary, reversal of the long-term shift away from credentials.

This particular example is not super important, but it made me realize something important about journalists. The percentage who are engaged in a disinterested search for the truth is close to zero. They nearly all write as controversialists. It's puzzling why this should be so. In principle the job of journalists is to tell us what's going on. Why would that require them always to take a position about what's happening? And yet that seems the default.

You still occasionally hear people saying that founders don't deserve to be rich, because their employees created all the value. But the falsity of this claim becomes increasingly obvious as automation enables founders to grow companies with fewer and fewer employees. In the limit case, you're left with just the founders. And we're not far from it. Instagram had only 13 employees when it was sold for a billion dollars.

One interesting thing about this exchange, which we take for granted because we're so used to it, is that the journalist is arguing for more censorship and the business person for less. For most of history it would have been the other way around. This shows the degree to which journalism, as a profession, has been captured by the politics of its practitioners. When one imagines a journalist now (I don't count Fox employees as actual journalists), one imagines someone who's left first and journalist second.

"A lot more people have what it takes to start some startup than realize it. A lot of people, perhaps all people, have some distinctive combination of abilities and interests. And a lot of those combinations match some startup idea."

foundersatwork.posthaven.com/grow-the-puzzl… I haven't read this since Jessica wrote it in 2018, and I'd forgotten how good it is. There's so much in here that I had a really hard time choosing a quote to post with it.
