Suddenly realizing the anti-education efforts of the Republican bunch, the Koch’s and all their ilk, is actually motivated by self-preservation. It’s harder to know how to kill your overlords if you never learn about anatomy to know what parts are fragile. For example, you’d never know that cutting the femoral arteries can be every bit as fatal as the carotids, or that when targeting the heart/lungs a knife blade in a vertical orientation would just get caught in the ribs, or that puncturing both lungs would also be extremely bad.
A gut wound that reaches the abdominal aorta very well could be death, but how many people even know where it is?
So many phones don’t have headphones jacks anymore, and Bluetooth is a bigger hastle than just plugging in a wire. And all the cheap ones use Micro-B instead of C for charging, so now you have to worry about two wires. USB-C/lightning to Aux adapters are unnecessarily uncommon and take the charging port. Same with wired headphones that have a USB-C or lightning jack.
The tech companies have made courtesy inconvenient.
