   This is an interesting read. I didn't get through all of nor did I delve into it more deeply but it does feel a bit like the tail wagging the dog. It seems pretty clear to me that post WWII, the USA poured significant investment into R

   There's a sentiment here that I think is valid and I'm struggling to tease out the best version of it, along with providing a valid response. I'll mention that, in an extreme case, one could provide a proof-of-work challenge

   Time delay, as you proposed, is easily defeated by concurrent connections. In some sense, you're sacrificing latency without sacrificing throughput. A bot network can make many connections at once, waiting until the timeout to get the

   > Software also has a (unique?) "win more" mechanic where a popular tool tends to get more popular. I don't think this is unique at all to software tools and is a general principle. Rosen had a paper in 1981 talking about

   The way you've described it, charging at your home takes 8+ hours. You can do other tasks in parallel, so the effective cost to you is 6 seconds but that doesn't change how long it takes to charge your vehicle. There are many use

    To further expand on this with some back-of-the-envelope calculation, I've heard EVs are on the order of 30-40 kWh. Say the power storage of the gas tank in an ICE car and the battery storage of an EV are commensurate. Conservatively,

    Again, cryptocurrency would allow a proof-of-work mechanism but offload it so it needn't be real-time. That is, do the proof-of-work before visiting the website, then present the currency token that proves the work has been done. The b

    I think these solutions are really novel and interesting but I'd like to point out that this is literally one of the use cases for cryptocurrency, or microtransactions in general. Cryptocurrencies, at least the PoW ones, offload the pr

    In my opinion, you've grossly mischaracterized and misunderstood the bitter lesson. The bitter lesson is not saying that brute force will win out against better algorithms, it's saying that simple, efficient algorithms, in a theor

    To me, the headline is a little misleading. From the first paragraph of the article: > ... 46 percent of all counties studied had at least one pharmacy desert, and that 15.8 million people in the U.S. live in pharmacy deserts. So while
