Asianometry’s YouTube channel has some of the most interesting and informative videos on semiconductor manufacturing and the history of electronics. He also has a catalog of his videos. Here is one which everyone who owns a smartphone or PC should watch to find out what is inside of their device.
2023-08-18 Ferroelectric Memory Transistor Demonstrated
Several decades ago I read about these new Josephson devices that the scientists had invented, and how they would do wonderful things in the future. Here we are decades later and we hear nothing about Josephson devices. So here’s another interesting device, it uses indium selenide. It sounds promising but it may end up like

2023-07-07 Tesla Sudden Acceleration Due To Voltage Spikes
This could affect all models. The heavy power could have caused a negative voltage spike that mimics a pressed accelerator. https://www.notebookcheck.net/Sudden-Tesla-acceleration-attributed-to-voltage-spikes-that-may-have-tricked-NHTSA-into-ruling-it-driver-error.732407.0.html
2023-06-27 The Reasons Behind The Chip Shortage (Sabine)
Very good video about the chip shortage. There were fires in several plants, natural disasters like the earthquake in Fukushima, and too much dependence on only a few factories. We need to prevent this from happening again.
