    AI 2027 remains annoyingly on schedule. Worth rereading the doc. If you think it’s too long, I listened to the audio version while I walked. https://ai-2027.com/

    Reminds me of 4dtoys, which does a great job introducing you to 4d interactions one step at a time. It’s great! https://4dtoys.com/

    Didn’t YC already try this with Yuri Milner ten or so years ago? From what I remember they canceled it because it was creating zombie companies, where the founders felt like they c…

    It seems like a lot of people are defending credit card pricing, but the idea that they’ve been charging the same % since before the internet and are still absorbing the same “cost…

    Here’s a nice takedown of Plomin’s theory. I’m not a geneticist, but there seem to be a lot of holes in it. https://www.nature.com/articles/d41586-018-06784-5

    To give some context, two to the 100th power is 1,267,650,600,228,229,401,496,703,205,376. Interesting description here! http://www.freemars.org/jeff/2exp100/answer.htm

    They mention that these pages were created for every combination of “connect service X to service Y”, which matches twhat people are actually looking for, so I would argue this is …

    When they say 5 million mph, is that relative to the center of the Milky Way?

    Amazing idea! I'd love it if the site could give some sense of how profitable the business could be, and over what timescale. I don't need specific numbers, just the fundamental ex…

    Which makes me wonder, why do they use their own domain instead of relying on npm?

    The difference is that the roll of a die is random, but the outcome of an election gets more deterministic as it approaches. Election prediction is figuring out what people have al…

    I would argue that buying a single stock is gambling, but buying into a fund, or taking the time to research and invest in hundreds of stocks, is investing.

    The difference is in expectation of return. In retrospect, bitcoin is a great "investment," but looking at the hundreds of other failed cryptocurrencies it's clear that early buyer…

    It's tempting to describe bitcoin as "investing", but it's really gambling. I could say I bought $30K in lottery tickets and ended up making a few million off it, but I wouldn't ca…
