I didn’t know IBM mainframes run the world? Just curious, care to expand?

  Banks run the world, IBM mainframes run the banks.

    >IBM mainframes run the banks. And the airlines, and the logistics companies

    That's a bit unfair to the insurance companies. They have a pretty big say in what happens and also run mainframes.

    And mainframes run on concrete floors, maybe construction companies run the world by that logic?
    • nerdo 4y ago
      Mainframes aren't a big truck, they're a series of concrete floors.

        My usual comparison is with cargo airplanes.

    This is becoming less true over time.

  many of the most core US IT infrastructure projects- government and commercial- depend on IBM 360 assembly code or another IBM system, written decades ago that has been repeatedly scaled to handle the increase in load. Two I can think of: SABRE and the IRS.

Personally I have a ton of respect for production systems that can be scaled in place for 50 years. But I don't have any interest in learning to run IBM mainframes or code for them- I'm preparing for lots of contract work in 2037.
