  • there’s been little progress toward creating the unfathomably long carbon fiber tether

    When space elevators were first discussed, there were no materials that could possibly be used. Now we have carbon nanotubes that may be strong enough. That’s huge progress.

    But yeah, the political issues will prevail. If we can’t even agree enough to build California high speed rail, think of the impossibility of a major infrastructure project several orders of magnitude bigger and more complex, several orders of magnitude more costly, and where a failure is essentially a weapon of mass destruction affecting hundreds of millions of people.





  • The problem with that logic is this is a residential area. Getting people out of cars and into cycling is great and reduces how often cars are needed. All good things, but probably not enough to eliminate the need for cars.

    When I lived downtown, I was able to walk or take the train almost everywhere. But there were always a few remaining things where I needed a car. It was great having the option to rarely use a car but I wasn’t able to get away from the need to have one. It greatly reduced how often I used a car but did not at all rescue that I needed a parking spot

    Assuming this is residential and the spots were needed, we’d be better off finding a long term storage solution for cars, an alternate location for vehicles that are needed but rarely used

    But I’ll agree with your logic if this is mostly retail



  • I’m more concerned about people wanting to use that to raise the retirement age.

    1. They don’t understand averages. Reducing childhood deaths significantly raises average life expectancy by increasing the number of people who reach retirement ages, not by making them more able to work
    2. Nothing forces people to retire at a specific age. I’m more concerned about being able to work long enough to afford retiring. “Retirement age” is 67 and I don’t expect to be able to work that long
    3. Ageism is a thing. As I’m approaching 60, I understand I may never be able to get hired again in my field. This may be my last job, whether I want that or not, and regardless of what retirement age is
    4. There is no such thing as retirement age in the us. There is only the age range at which social security will start paying out. That has nothing to do with how old you need to keep working, how old you can keep working, or how old you’re allowed to keep working


  • On the surface, this could be entirely legit, not worth the outrage.

    I can easily believe

    • regulations are not ready for self-driving vehicles
    • a manufacturer decided some required equipment is not suited for a car meant to be self-driving only
    • the manufacturer self-certified, with exemptions where there is no regulatory framework yet.
    • government agency sees that and starts an investigation to see if they agree

    Even before you get into what you think of this specific manufacturer and whether they’re really ready for self-driving, this is a “normal” process

    I’m more worried about regulations defining what self driving needs to be capable of and tests to qualify it

    Whether a cyberCab is capable of safely self-driving is a different question from whether a self-driving vehicle is required to have a steering wheel








  • Dust devil maybe? I’ve seen those several times, never strong enough to damage anything.

    I don’t know if this counts but I found a courtyard between buildings on Manhattan where there was always a swirl of wind at a specific spot from prevailing winds being funneled between buildings. A bunch of time I went back there I’d see a swirl of leaves and trash like a mini-tornado, always in the same spot




  • Yeah I think the timing was critical. She started campaigning way too late.

    I do think Biden did a good job and got a lot of things moving in the right direction. I also think too many of the things he started were too long term: “continue the same policies” was the best answer. However we as a country no longer have the patience, we need instanteous gratuity that was just not there. It’s somewhat like the Jimmy Carter problem: it doesn’t matter how smart you are or whether you’re doing the right thing if you can’t get everyone excited.

    Harris started off strong but really didn’t get anyone excited and “more of the same” was not the way to do it (even if she were right).

    She needed time and distance to better establish her as a distinct candidate.

    I even see Biden’s logic of “can’t let Trump win and no other candidates stand out” but it was the wrong approach. In hindsight, yes, dropping out much earlier was clearly the better choice
