The hilarity is in everybody fighting for their antique technology's supremacy. Silicon Valley was built ignoring the engineer's maxim of waste heat undermining efficiency. I lived there. I heard very rich tech people ridiculing efficiency as their products require massive cooling infrastructure as the planet's potable water disappears. They change the subject when you ask about superconductors, or even an inverter that will last longer than a pair of socks.
The Rapid Rise (& Fall) of the CD
A few days ago, one of my favorite YouTube channels did a video on the CD. This channel (Asianometry) always does an incredible job telling the story of different technologies, technical industries and/or products.
I think most of you will find the 25 minute video to be very interesting.
