The article is much funnier than the video. At least for those of us that actually still read books on our iPads. A few of us even remember paper which we enjoyed recycling before we ever had a chance to read all the articles in EE Times. I enjoyed the creativity.
A curmudgeon after my own heart. They started taking the serial and parallel ports away with XP when they stopped letting you access them for bit banging without installing a driver. Now you need to install drivers and hardware to simulate a serial port on USB like the FTDI stuff. You see they needed to protect the computer from the user. The modern computer design philosophy is that it is not your computer. Microsoft, Oracle, Adobe and Google should be allowed unfettered access to your computer while you as the user should only be allowed the minimal access that they determine you need. WiFi and USB are major advances in monitoring, controlling and limiting the user's use of the computer.
Completely disagree with the criticism of USB. USB automates the negotiation of the data rate, error correction, and other settings that used to be done manually. And while using serial to Ethernet converters is convenient for legacy hardware -- the real fix is to place Ethernet interface directly on SCADA or PLC gear.
As an engineer who uses all of these technologies, I found nothing useful or insightful from the video. Granted it has some humor (about social networking). But that wasn't why Ethernet was invented.
