Corporations will, 99% of the time, take things you bought away from you if... 1. They are not making (enough) money on them any more 2. They can and get away with it Simply because they want to clear the stage of all competition for their next offering, including old offerings you may be happy with...
A good example is perfectly good wired headphones (which can last 10+ years at least with proper care and maintenance) being swept aside for battery-powered wireless options which are 1) incompatible with older devices and 2) will die after enough battery charge-discharge cycles, forcing you to buy a new one.
the real shit is good drivers and a user-replaceable cable. a little more up front but you can still replace the part that usually breaks for cheap and they sound way better.
she meant "apropos". it's a non-sequitur but she is speculating about what would happen if the primary sources our society uses for standard time stopped communicating
All digital infrastructure would collapse if our society lost its ability to coordinate on time, but I don't see how this would affect Bluetooth headphones.
I'm generally doing a lot of movement while wearing headphones, whether it's walking, working, or cycling, so I've found wireless headphones have lasted much longer than my old wired ones as well as being more convenient.
Wired headphones do have a bunch of advantages, but so do wireless, and product lifetime isn't a great measurement when it's dependent on use.
edit: A better example would be smartphones, with support for models being dropped within a few years, and them slowly becoming more and more incompatible with new features, regardless of their physical condition.
