  • The raison d’être for RISC-V is domain-specific architecture. Currently, computational demands are growing exponentially (especially with AI), but Moore’s Law is ending, which means we can no longer meet our computational demands by scaling single-core speed on general-purpose CPUs. Instead, we are needing to create custom architectures for handling particular computational loads to eke out more performance. Things like NPUs, TPUs, etc.

    The trouble is designing and producing these domain-specific architectures is expensive af, especially given the closed-source nature of computer hardware at the moment. And all that time, effort, and money just to produce a niche chip used for a niche application? The economics don’t economic.

    But with an open ISA like RISC-V, it’s both possible and legal to do things like create an open-source chip design and put it on GitHub. In fact, several of those exist already. This significantly lowers the costs of designing domain-specific architectures, as you can now just fork an existing chip and make some domain-specific modifications/additions. A great example of this is PERCIVAL: Open-Source Posit RISC-V Core with Quire Capability. You could clone their repo and spin up their custom RISC-V posit chip on an FPGA today if you wanted to.




  • NYC itself doesn’t have much (although it still has some! see image below) low-density zoning, but their suburbs sure do. The city itself also has a lot of other bureaucratic barriers to development that result in it having abysmal housing construction rates.

    As for vacancy, yes, the threat of not being able to sell is what stops builders from building too much. For example, it’s the reason no one’s even trying to build the Burj Khalifa in Bakersfield. But if you make it legal and reasonably easy to build, yes, people will build.

    Perhaps Tokyo is the best example. Biggest city in the world, and yet it’s actually relatively affordable, thanks largely to good land use policy:

    In the past half century, by investing in transit and allowing development, the city has added more housing units than the total number of units in New York City. It has remained affordable by becoming the world’s largest city. It has become the world’s largest city by remaining affordable.

    Two full-time workers earning Tokyo’s minimum wage can comfortably afford the average rent for a two-bedroom apartment in six of the city’s 23 wards. By contrast, two people working minimum-wage jobs cannot afford the average rent for a two-bedroom apartment in any of the 23 counties in the New York metropolitan area.

    In Tokyo, by contrast, there is little public or subsidized housing. Instead, the government has focused on making it easy for developers to build. A national zoning law, for example, sharply limits the ability of local governments to impede development. Instead of allowing the people who live in a neighborhood to prevent others from living there, Japan has shifted decision-making to the representatives of the entire population, allowing a better balance between the interests of current residents and of everyone who might live in that place. Small apartment buildings can be built almost anywhere, and larger structures are allowed on a vast majority of urban land. Even in areas designated for offices, homes are permitted. After Tokyo’s office market crashed in the 1990s, developers started building apartments on land they had purchased for office buildings.

    I think the key idea is to not have government bureaucrats or existing homeowners or landlords decide whether there’s “enough” housing, but rather let builders determine if there’s unmet demand. If there is unmet demand, they will build if you let them. If there truly is enough housing in a certain city, then you don’t need to tell builders not to build – they’ll simply stop building if they sense there’s not enough demand for it.


  • The “we have enough homes already” is a common (and unfortunately very harmful) myth.

    A couple good in-depth videos on the topic:

    The gist of it is that statistics on how many vacant homes exist are highly misleading, for two main reasons:

    1. Many of the homes are not where the demand is. A vacant home in St Louis does nothing to help with a housing shortage in NYC. People want to live in NYC because that’s where the jobs are. A house in St Louis isn’t worth much if you can’t find work there. And statistics consistently show that the most expensive cities have the lowest vacancy rates.
    2. A lot of the homes that are counted as “vacant” aren’t actually just free for the taking like “vacant” would have you believe. In these statistics, “vacant” can mean: 1) a unit that is between tenants, 2) a unit that just finished being built and is awaiting its tenant’s move-in, 3) a unit occupied by someone who doesn’t legally state it as their primary residence (e.g., student housing where the student still lists their parents’ home as their primary address), 4) a unit in horrible disrepair that is unfit for occupation, etc.

    Add to this the fact that high vacancy rates are GOOD for you, as it means landlords and sellers have a credible threat of vacancy, meaning they can’t demand ludicrous prices. Reducing vacancy rates is an incredibly anti-consumer, pro-landlord move.


  • Yeah, political opinions based on “regulations always good” or “regulations always bad” are lazy and unhelpful. For one, it ignores that many regulations are written for the express purpose of manufacturing or solidifying a monopoly.

    Regulatory capture

    And NIMBY land use policies really are just a textbook example of regulatory capture. Homeowners, who expect their homes to perpetually increase in value, lobby their local governments to manufacture an artificial scarcity of housing so as to drive their property values to the moon. All of this at the expense of renters and new home buyers.

    Imo, we should all be trying to form nuanced political opinions where we judge policy on whether it’s good policy or not.



  • Exactly. When the accused has paid off half the jury, you shouldn’t put much stock in the verdict.

    The only thing I care about when determining whether something is a genocide is the facts of the case (which are overwhelmingly in favor of describing the Uyghur genocide as a genocide), not the outcome of a highly political vote by countries all with their own motives and interests.

    I agree that I think worker coops elegantly solve certain problems (notably the principal-agent problem), but they also have certain drawbacks. Notably, they have more difficulty raising funds, they tend to be more risk-averse, they tend to be more growth-averse (people don’t like to dilute their own stake within the company with more people, but this means they don’t typically scale as easily or quickly to benefit economies of scale), and they tend to pay worse than hierarchical companies (counterintuitive as that may seem at first if the whole goal of market socialism is to have workers get more of their value back).

    So is the solution to just throw our hands up and say, “Screw it, nothing we can do but let hierarchical organizations win”? Not quite. We still do see plenty of successful coops, notably in the form of credit unions. We also have unions and syndicalist solutions. We still have minimum wages (which are supported by most economists, as it turns out you can raise minimum wages a certain amount without raising unemployment because there’s often a non-zero amount of monopsony power in the labor market).

    Further, I do think a Georgist system would empower labor much more than now. Without a housing crisis (thanks to LVT and YIMBYism), with a citizen’s dividend, with quality public education (education has positive externalities and thus deserves a Pigouvian subsidy), with more jobs (thanks to more economic growth and less rent-seeking), and with public works projects (essentially Pigouvian subsidies for things like environmental cleanup), I think labor would have much more bargaining power with employers.

    For instance, the professional class right now gets good pay and generally good quality of life , despite rarely having unions or worker coops, precisely because they have high negotiating power with prospective employers.

    My inclination is to strive for a more Georgist system, encourage unions, use minimum wages and government spending technocratically, and then see if more is yet needed.

    But society already values flexibility as well. As a basic example, I was hired in my current job in large part because I have a relatively broad range of skills within my field, rather than being hyper-specialized in one particular thing. Sure, in an abstract world where replacing employees is frictionless and firms are all megacorps with tens of thousands of employees (or more), tremendous specialization would probably be more commonplace. But in our real world, companies value flexible employees who can respond to changing projects, requirements, conditions, etc., because just firing and hiring a new specialist costs times and money, and many companies (startups especially) can’t afford having thousands of specialists in every niche they touch upon.

    Further, even specialists have to communicate and collaborate with other specialists, and they need to be able to understand each other well enough to do so. If you wanted to build robotics to pick tomatoes automatically, for instance, it would be ridiculous to hire one tomato farmer and one roboticist who know nothing about each other’s respective specializations. If neither has any flexibility or breadth of knowledge, it will be very difficult for them to communicate and collaborate to get the project working.

    People live in an artificial binary where they believe communism and capitalism are the only two economic systems in the entire world.

    I’ll be bold and say it outright: communism is a fundamentally broken idea and sucks balls, and so is capitalism, but both in similar-yet-different ways.

    Communism is faulty economics and fails to differentiate between man-made capital and god-given land and natural resources, grouping both as “the means of production”. The problem with this is land and capital have very different properties. Where land (and natural resources) cannot be created and are zero-sum, capital must be created and is not zero-sum. Communism blatantly ignores this and has a zero-sum view on capital, meaning it suggests policies that fail to effectively produce new capital, and thus fail to effectively produce new wealth and prosperity. Further, when the state takes monopolistic control over land and capital (in addition to its existing monopoly on violence), it concentrates far too much power, which is why communist countries keep on becoming brutal dictatorships.

    Capitalism, on the other hand, also fails to differentiate between land and capital, but in a different way. Instead of socializing both, it privatizes both, allowing massive rent-seeking and exploitation as a result of monopolization of land and natural resources. It also often willfully ignores that negative externalities and other market failures actually make society, on the net, poorer and less prosperous. Further, this concentration of wealth into the rent-seeking, monopolist class grants them more political power to make it even easier to rent-seek, further concentrating their own power and wealth.

    What I want instead is a Georgist system that correctly identifies this distinction between land and capital, and then uses economically proven policies that respect the inherent differences between land and capital.


  • Sounds similar to some of the research my sister has done in her PhD so far. As I understand, she had a bunch of snapshots of proteins from a cryo electron microscope, but these snapshots are 2D. She used ML to construct 3D shapes of different types of proteins. And finding the shape of a protein is important because the shape defines the function. It’s crazy stuff that would be ludicrously difficult and time-consuming to try to do manually.

    Wow, even Terre Haute. Almost went there for college (Rose-Hulman), but decided against it in part because the city itself was so small and sprawling. It must’ve been 1000x livelier back in the streetcar days when things were probably more densely built and less obscenely car-centric.

    Also, Trump got elected, so I was like, “Nah, I’m moving to Canada”, which is how I ended up in Montreal instead.
