A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

Telegraph and wire transfers were a thing 100 years ago, you could say "Everyone have a telegraph at home. Private communication, for example orders to your bank to wire money, uses codes/cyphers that can be decoded if the third party was smart enough".

You'd have to go back before the discovery of electricity, and even then you could make an analogy with lighthouses (which isn't really a stretch, as fiber optic cables can be described as point-to-point light houses), and most people at most periods are probably familiar with the idea of talking in codes.

Technology isn't really that hard to explain. Social change is much harder. Try explaining to someone from 1920 that the US had a black president and nothing catastrophical happened, or that all professions today are open to women and you'd have a much harder time.

They used encryption when using carrior pigeons for centuries. Pretty easy to explain the concepts when, for example, MTM attacks were actually happening thousands of years ago.
