       +Wires! Cables! Connectors!
       +Computer and electric systems seems to befriend with plugs and sockets.
       +Why is the computer industry running away from them for everything exposed to users?
       +.
       +.IP "Where do I plug the cable?"
       +Everyone needfully face this question at least once, be it the first time they own a computer.
       +From the various connector shapes to choose from, to the various set of protocol the Universal USB connector supports,
       +cables provoke confusion to cable-haters and computer neophytes.
       +.
       +.IP "Cables are ugly"
       +It might not be true for everyone, but computer manufacturers seems to say differently.
       +Starting with the name "wireless", that comes by opposition to wires, supposing they were something to avoid.
       +Cable management is a full time job for datacenter jockeys, and a chore for the cable-hating computer user.
       +.
       +.IP "Cables are immobile"
       +Unless making use of an uncommon cable management strategy,
       +objects connected to cables cannot be carried too far away without unplugging everything devices are connected to.

       +So here comes wireless.
       +While not frequent in large computer infrastructure, wireless is invading the market along with battery devices.
       +Using radio waves to make device talk to each other, at various frequencies, modulation, datarate and distance.
       +Ready to sacrifice any amount of good engineering to make itself more seducing to the market,
       +marketting perpetuates the same illusion of making computer troubles fade away with wireless.

       +From the Bluetooth protocol swamp of mixed edge-cases and compmlexity,
       +to the security vulnerabilities of Wi-Fi,
       +to the security vulnerabilities of Bluetooth,
       +to the proprietary but popular protocols like LoRaWan,
       +to the unreliability and unstability as opposed to wires,
       +to the black box of wireless broadband such as UTMS and LTE,
       +Wireless does not have the same fame among developers valuing simplicity and reliability.
       +.
       +.PP
       +Even the United Army holds griefs against wireless such as Bluetooth,
       +and disrecommand it for use by militaries:

       +Nontheless, wireless is fun, beautiful, and filled with culture.
       +While marketting pushed engineers from the wireless cliff,
       +long before computer came, radio waves were put at good use in the most simple forms: radio communication.
       +From the AM and FM radio stations to listen while on the road,
       +the medium-range boat, airplane, truck, pedestrian talkies, and even satellite communications,
