  • And how do we cross the oceans?

    Let’s see even a high speed train cross the US, from LA to NY. Every state will want it to stop in at least one major city, or they simply won’t vote to subsidize it.

    Not to mention the land required - find a way to acquire the land between LA and NY to support it. Same problem as above.

    All this without even approaching the flexibility issues, and many more.

    While planes can go wherever, so long as the airport supports that class of plane (length/weight).

    Trains have their place, in well-established routes that don’t change much. They can tolerate increased use to some degree, but as soon as you lose ridership, costs per traveler balloon.

    And they still require many tons of concrete, as the bed for high speed has to be even more stable than for an interstate.

    And, you’re still accelerating (start/stop) many tons, regardless of how many passengers are on board.

    Trains aren’t a panacea, not a free lunch.





  • And there will be another currency after that.

    Again, I’m not spending my time bartering the chickens my boss gave me for some crabs, for some iron, for some gas, just to trade that with the person that has the thing I need, because thats what they wanted.

    If you come up with any argument about “well my simplifies that by making the trades for you”, then you’ve just re-engineered currency.

    Currency isn’t the issue, it’s money lenders (you know, the table Jesus supposedly threw over at the synagogue), because it’s the generation of debt to make profit at the expense of others, while not contributing anything tangible, that’s the problem according to the parable.

    You could still have debtors in a barter system, and that would still be problematic. It would still be debtors preying on people with little to start with, like payday loan places. “We’ll loan you 2 chickens today, but you’ll owe us 3 on pay day”. See, no difference.

    Now if you want to make a local barter system just because, that’s different. But acting like you’re going to replace currency is naive, at best. Currency has been with mankind for thousands of years, because it simplifies trading.



  • The thing is that with progressive bifocals, and the right size lense, this is rarely an issue, as you choose the focus you need by simply moving your eyes and head. When setup properly I rarely need to move my head at all for normal day-to-day stuff, as we naturally put what we’re viewing in the center of our vision.

    For example, when looking far, we tend to look upward more, so naturally use the upper portion of a lense. When on a computer or reading, we tend to look downward. Driving is a great example, we look forward and up while driving, down to see the dash, and progressives cover that with no problem.

    The only time I run into “problems” is when doing really close work for an extended period, like stuff inches from my face. But for those times, I just switch to readers only while I’m doing that work. These glasses could maybe work there.
