🕹 Technology Telecommunications
  1. Thaddeus Cahill invented an early electronic music system called the Telharmonium in 1897, aiming to broadcast music through telephone lines. However, his venture failed because the music interrupted phone calls, causing complaints from users.
  2. Cahill's difficulties were largely due to a problem called cross coupling, where signals from one line affect nearby lines. This was common back in the day when many phone lines ran close together.
  3. The situation shows that electrical signals can spread beyond their wires, not just following what we'd think of as direct paths. This understanding is important in telecommunications and electrical engineering.

The Unbreakable Message

Who is Robert Malone • 15 implied HN points • 28 Feb 26
🕹 Technology Telecommunications
  1. Quantum communication uses quantum physics to make eavesdropping detectable, so intercepted messages can't be silently copied or later decrypted. This prevents the "harvest now, decrypt later" threat.
  2. Militaries, intelligence agencies, and banks are prioritizing quantum links for the most sensitive communications because the technology can provide a lasting strategic advantage. Whoever builds the networks and standards first could shape the global information architecture and force others to choose sides.
  3. Practical limits remain—photons are lost in fiber, quantum repeaters are needed, and current hardware is expensive and low-bandwidth—so broad consumer use is likely decades away. Once repeaters and miniaturization mature, a quantum internet and distributed quantum computing could reshape security, finance, healthcare, and science.
