  • CDs were a massive improvement, and the pinnacle were DDD CDs, which were Digital recording, Digital mixing, and Digital mastering, meaning very little analog garbage was introduced in the process.

    Very little analog garbage... Except for literally every instrument tracked in, including distortion pedals. :)

  • Whoops, there you go again comparing the impact and resolution of a single cable to an entire national network.

    That's... um... how it works? It's generally one, maybe two, cables connecting continents: https://dabrownstein.com/2015/06/30/charting-interconnectedness-in-undersea-internet-cables/

    I mean, some continents, like the US, have myriad cables connecting. And purposefully sabotaging these is almost as challenging as repairing them.

    So, generally, "nations" are not connected via undersea cables, continents are.

    So, yes, repairing one, maybe two, would be reconnecting an entire national network. Which is STILL cheaper than replacing a mass of Starlink sats... Which, btw, need replacing routinely anyways, because their orbits decay purposefully.

    So, every 5 years, we need spend tens of billions to launch another set of trains, just to have them fall into the ocean after 5 years of service. Just to obtain a service that is cheaper, and doesn't require nearly as much regular investment if we just used fiber.

    I get the feeling you don't understand the economics, physics, and infrastructure of various connectivity systems. And, you also don't understand that without connected ground stations, served by those "at risk fiber networks on the ground" (That you purport as very risky), Starlink doesn't work, either.

  • You understand EMPs wouldn't affect one sat, right? Or a capture net can hit an entire train?

    If you want to compare accurately, look at the time it takes to replace the cable infrastructure for an entire nation vs the time it takes to relaunch all the star link satellites.

    That can, and has been done in a couple of weeks. It happens somewhat regularly.

    10-20 days to launch a repair crew, and another week to affect the repair. At a few hundred million in costs.

    A single rocket launch it minimally a year of planning. And BILLIONS in costs.

    We started using satellites in the first place because it was the fastest (and in many cases, cheapest) way to get TV coverage anywhere on the planet.

    Well, yes, because they are placed in a high orbit (Not LEO) generally, in order to cover massive patterns with ONE WAY signalling (Aside from the one uplink).

    This is a host of difference between myriad 2-way ground stations.

  • My fiber ISP runs single mode to my home. And it means it's all single mode on the pole for the neighborhood.

    Multimode just isn't used all that much anymore. We replaced all fiber links in our DCs with single mode recently. It's just cheaper, and as the other person said: Its far more future proof.

  • Starlink works well in tandem with fiber, not as a replacement.

    It doesn't even work well in tandem.

    Starlink has a single benefit going for it right now: Lack of uptake.

    They only have a swath of spectrum, and that has a physical upper limit to how much information it can carry, in total. So does fiber. But, Starlink gets to share that with all users (Much like how cable internet works, its shared bandwidth for everyone on the loop). Fiber, you get your dedicated pipe.

    This isn't even getting to view obstruction (A plane will cause a drop out), latency, jitter, etc. These are all physics problem that just cannot be solved without violating the laws of physics. Latency, at a minimum, is 2.6 ms, and that's just for the first leg.

  • Spoken like someone who has never had some idiot in a backhoe chop a fiber bundle…multiple times in a week.

    And, when it happens, it generally gets repaired in hours. You cannot launch a new constellation in hours.

  • Except StarLink cannot possibly provide the same bandwidth, latency, and throughput a fiber connection can. Because of physics.

    I can either share my 10G symmetrical connection with nobody, or with 200 others.

    And, Fiber costs me $70 a month. Starlink, with worse performance, costs 4x more.

  • Cheering for Cloudflare to be the arbiter of what technologies are allowed is incredibly short sighted

    Except, they don't. It's a toggle, available to users, and by default, allows Perplexity's scraping.

  • I think it boils down to "consent" and "remuneration".

    I run a website, that I do not consent to being accessed for LLMs. However, should LLMs use my content, I should be compensated for such use.

    So, these LLM startups ignore both consent, and the idea of remuneration.

    Most of these concepts have already been figured out for the purpose of law, if we consider websites much akin to real estate: Then, the typical trespass laws, compensatory usage, and hell, even eminent domain if needed ie, a city government can "take over" the boosted post feature to make sure alerts get pushed as widely and quickly as possible.

  • You could probably route all requests to your site from them, back at themselves, so they DDoS themselves, and on top off it, cost them more because their endpoint needs to process things via their LLM.
