  • You underestimate how affordable or accessible a computer was in the eastern block. For reference, a color tv that is “mass produced” and didn’t need much expensive high tech parts would cost as much as you would earn in one year - if you manage to find one in a shop.

    For a computer you needed to find keyboard, drive, monitor, software and the computer itself which would be at least equally expensive to a color tv.

    All the chips had to be manufactured locally in the eastern block, because there was an embargo on western computer tech. RAM alone was 10x more expensive because the manufacturing process was very inefficient.















  • While i would love to travel by airship, I dont think there would be a commercial success in airship passenger travel in the near future:

    • travel times of multiple days means you probably need 2-3x the crew, compared with a plane on a 8h flight
    • this also means a plane that is 4x as fast can make the same trip 4x more often, bringing in more money for the airline in the same amount of time
    • you probably can’t land on existing airports, because an airship the size of a large building would be crawling accross your airspace blocking all flight traffic, or shaken by the turbulences behind a large jet powered airliner
    • new technology without any existing infrastructure is much more expensive than building on top of existing things
    • tickets would be much more expensive than a commercial plane because of the reasons above, the lower passenger capacity and the fact that you have to carry more supplies (water + food for days multiplied by people on board) for a longer trip. Each passenger with cabin and supplies was calculated as 300kg weight on a transatlantic flight on the hindenburg
    • Hindenburg could not fly in a direct straight line, because it travels at a height of only 400-600m. This means you had to go around high mountain ranges, because people and the combustion engines need oxygen which you dont have much above 4000m. However i dont know if this is still a problem with modern pressurized cabins, or if there is another limitation from the lifting gas…
