   This is an interesting way to look at it! I think one missing piece that’s far from mature is data fetching. It’s really hard to get something working well at scale: - REST is simple, but you end up with serial waterfalls for complex fetche

   That already exists. Maybe it’s more about authorities changing their opinions as a bloc, similar to how OPEC adjusts oil prices as a bloc? (The issue isn’t that any one oil company sets prices, but that companies form a cartel that collude

   Seems like this might still run into the same problem. People naturally look to authority figures for what to think about the issues, and even without political parties this will still be the case. The deeper problem is people who broadcast

   Automatic TCO affects stack traces, which programs might rely on at runtime, requiring that browsers agree on what the right behavior should be; on the flip side, manual TCO (with annotations) would need to be a language feature.

   Is that Crystallizing Public Opinion? Will read next. Lippmann says the answer is two parts: 1. For voters, improve their ability to make the right choice via education and representative (not direct) democracy. 2. For politicians, improve

   I just finished Lippmann’s 1922 classic Public Opinion. In it he argues that different people may draw completely different conclusions from the same facts due to three things: 1. Sampling. There’s a big universe of facts, and each media ou

    This is a great point. Can anyone find a link to the raw dataset? Happy to whip up a better visualization.

    Maybe. I’d be curious to see a breakdown of a traditional broker’s revenue compared to Robinhood. I bet Robinhood makes most of its money off order flow (it was founded by HFT traders, after all), while traditional brokers make more money o

    That’s not the problem with making money off order flow. The problem is that it fundamentally misaligns incentives: while Robinhood makes money the more people transact (and is the reason its fee structure and UX incentivize transacting), i

    Some might argue it’s precisely this good UX and low fees that incentivize risk-seeking behavior in a set of users who are largely uneducated about the risks of frequent trading, margin, investing on gut feel, etc.

    Warning: fellow engineer here. I am not a financial advisor. You can follow one of two stock-based strategies: 1. Invest 100% in an S&P500 index fund, returning 8%/year [1] and growing to $11M in 30 years [2], minus withdrawals. 2.

    Zero trust + distributed consensus seem like overkill for this. Why not use the govt as an authoritative record keeper?

    It takes a lot of experience to build the intuition to make the right technical tradeoffs, choose the right architecture, escalate staffing gaps, forecast timelines, rope in the right folks, etc. It’s not something you can learn in school,

    I’m hearing a lot of theories in this thread about Apple building a search product. Yes, that’s possible, but Applebot is used in a lot of ways today that are wholly unrelated to search. (If search consists of crawling, indexing, ranking, r

    I wonder if you could approach this like you’d approach designing any other data structure, by first nailing down what operations you are optimizing for. We could optimize for ease of iterating on the compiler, or for ease of integration in

    I hear the frustration in your comment, and I wonder if it’s because you might not be using TS correctly. When used right: TS infers most of your types, TS does not add to the lines of code you need to write to get something done (especiall
