  • I’m more skeptical than most that self driving will be properly solved anytime in the next few decades, but I really doubt the article’s claims that it will be able to claim much modeshare from bikes and transit.

    Firstly, we already have and have had autonomous vehicles for nearly as long as we have had vehicles, their called taxis and carpools. Making these potentially cheaper, though in practice I doubt it since a taxi’s costs are spread over all its users while a car has to be paid by just you, does not change the fact that they are less convienent than being able to show up and hop on like a bus, or the immunity to traffic delays of rail. Indeed the proposed system of distant out of city parking lots would take more planning than just parking your own vehicle today in most places, as you have to call or order ahead with AVs to have them ready for instead of waking to your car and jumping in. Similarly, getting stuck in traffic does not get much more fun simply because someone else is driving, especially if you can’t even talk to them.

    The arguement for them replacing bikes is even worse, because one of the few things proper self driving vehicles are already pretty good at thanks to 360 ultrasonic and lidar sensors at is not blindly running down bikes, and a future with widespread adoption would also imply that most other vehicles have similar driver assistance tech, and as such more people will feel safe biking even in places with shit bike infrastructure. Meanwhile most people who were going to use a bike for a trip will not choose driving over bikeing just because they can get someone else to come pick them up.

    I could see it having an effect on modeshare in places with really shit and infrequent transit, but the whole point of rapid transit is that it is more rapid than taking a car. If your transit system is slower and worse than waiting ten minutes in the rain for an Uber, fix your terrible transit system, because that really should be a low bar to clear.






  • Yes lightning, the network of centralized trusted third party banks that are needed to make bitcoin useable so long as you deposit all the bitcoin you want to use into one of these centralized banks first, at which point they can make bank to bank transfers without having any involvement with the actual bitcoin network at all.

    Or you could do basically the same process with an actual Debit card, which does the same thing but can be used in actual stores.

    You also need to note that for something posturing itself as a currency, the fact that you either have to wait hours or days for the price per transaction to come down or spend an even more absurd transaction fee on you’re cup of coffee before you can check out is actually a rather fundamental problem.



  • It means that despite being fifteen years old, it still takes more electricity for a single bitcoin transaction than to drive an electric SUV from Florida to California, cost per single transaction has still spiked over 50 USD twice in the last six months, and it remains too prone to wild inflation and deflation for any serious business to actually price anything in.

    In other words, it has the same inherent value it always has, none at all.







  • “A computer can never be held accountable, therefore a computer must never make a management decision.”

    Even more importantly when it comes to assessing properly, machine learning, now referred to as AI, has been continuealy shown to not just repeat the biases in its training data, but to significantly exaggerate them.

    Given how significantly and explicitly race has been used to determine and guide so much property and neighborhood development in the training data, I do not look forward to seeing a system that is not only more racist than a post war city council choosing where to build new moterways but which is sold and treated as infallible by the humans operating and litigating it.

    Given the deaths and disaster created by the Horizon Post Office Scandel, I also very much do not look forward to the widespread adoption of software which is inherently and provablly far less accurate, reliable, and auditable than the Horizon software. At least that could only ruin your life if you were a Postmaster and not just any member of the general public who isn’t rich enough to have your affairs handled by a human.

    But hey, on the bright side, if Horizon set UK legal precedent than any person or property agent is fully and unequivocally legally liable for the output of any software they use, after the first few are found guilty for things the procedural text generator they used wrote people might decide its not worth the risk.



  • Please explain to me how any of the child level explanation of the stock market is obfuscation, or again how you think the market cap, a purely theoretical number, could possibly be redistributed to employees outside of things the company already does to some extent, and finally why it applies in this case with a company who’s stock price is based purely on speculation about what it could do in the future and not anything it’s employees are currently doing.

    Also from your comment about how share price literally is the only measure of value for a company I’m taking it you follow the theroy of value that value directly equals the amount of money paid for it, which seems inherently contradictory to this entire conversation.


  • Technically, they don’t even make the actual graphics cards, they just design them and then outsource manufacturing to TSMC.

    But don’t you know that doesn’t matter, because by 2028 every singe company in the world is going to need a data center filled with tens of thousands of AI accelerators turning their own scrape of the internet into a chatbot, and so one of the companies that makes thouse accelerators is definitely going to have as much business as companies that make half of everyone’s phones or computer software./s


  • Firstly it shows the value of individual shares multiplied by the number of shares, not the company as a whole. Secondly, in this case Nvidia’s share price is based on what the company may be able to expand to do in the future, not what it currently does. Thirdly, where would this repersentive percentage come from? If it’s, issueing new stock to employees, A Nvida already does that a lot, B, creating new stock is not practically reliant on overall market cap so why is it relevant, and C, would employees also be punished for destroying the valuation if it turns out that every company doesn’t actually need a data center full of several thousand AI accelerators scraping the internet to make unique chat bots and Nvida’s market cap falls back down to what it would be based on how much money the company actually makes?

    Again, Nvida primarily makes chip designs for outsourced fabrication, not market cap, that three trillion isn’t like revenue for Nvidia. In your painting example, market cap would be like if two unrelated billionaires bet 10 billion on whether or not that painter would be successful in selling a hundred different 1m paintings in the next six months, the painter might have an easier time say getting a loan for new supplies from a bank if they can point to the billionaire betting so much on them, but you know it’s not like the painter was actually paid that 10 billion that makes up the bet, right? So it’s kind of weird to say that the painter’s work as a whole is definitely worth that 10 billion bet.


  • I’m saying that while a companies market capitalization is a real number that can tell you things about a company, it is not like anyone involved has a three trillion actual dollars. The company doesn’t see any of that money directly unless they directly issue more stock which would devalue the current stock, though there are some other ways for a company to use it to their advantage. Investors might be able to get a small percentage of that by selling, but only because someone else bought in with an equal amount of money, and a large sell will drive down the price.

    More to the point, the evaluations people are doing with Nvidia don’t have much to do with what the company actually produces and puts out into the world today, but the assumption that it can turn its current leadership position in AI accelerator chip designs into growing massively in size in the future when every company needs a large data center or two to train their own individual LLM’s.

    A individual stocks price is driven primarily by what people think that individual stock certificate can be sold for in the future, and effected by things like how many people are trying to sell, adding all of those certificates up at current market price doesn’t actually give anyone involved much information, nor does it reflect the actual quality, quantity, material, or labor taken to make things, in this case branded computer chip blueprints, that a company puts out into the world.

    Now there are a lot of competing theories of ways to try and measure labor’s value, but my work being only as valuable as the speculative amount my organization as a whole might be theoretically sold for as a whole in the future if no one tries to undercut anyone else isn’t one of the more popular ones.
