The technology of communications is impressive ... the use of communications potentially destablizing

Amazing progress / Plugboard 1960s / Cloud servers / IoT / 3D printing

Brief background about communications technology deployment in the USA
First, for context, here’s what each wireless generation has enabled since 1G in 1983:
• 1G (deployed in the 1980s): Analog cellular technology, very low bandwidth, designed to enable mobile phone calls
• 2G (deployed in the 1990s): Digital cellular technology, digital voice phone calls, enabled SMS (short messaging service – sending texts)
• 3G (deployed in the 2000s): Widespread use of CDMA (code-division multiple access) technology, high-quality audio for calls, early stages of low-quality video over mobile, and internet access
• 4G (deployed in the 2010s): Significant increase in data bandwidth, enabling internet browsing and streaming of high-quality video, voice-over IP technology (basically, free phone calls anywhere in the world using services like Skype or any kind of messaging application)

TrueValueMetrics (TVM) is an Open Source / Open Knowledge initiative. It has been funded by family and friends. TVM is a 'big idea' that has the potential to be a game changer. The goal is for it to remain an open access initiative.
WE WANT TO MAINTAIN AN OPEN KNOWLEDGE MODEL
A MODEST DONATION WILL HELP MAKE THAT HAPPEN
