When Apple dropped the optical drive, the internet was eating everything. The internet is a massive, global infrastructure project that was clearly not going to slow down. People were already downloading software, movies and music, and loved the ease of that experience. The writing was on the wall, they just jumped earlier.

So what's the up and coming thing that's just about to take over audio transmission, the "internet" that ate physical disk distribution? Is it Bluetooth?

> Bluetooth audio works perfectly fine, and it's how I play music on my headphones...

sample size of one. I can match that. I never use bluetooth and actively avoid it due to it's poor quality, connection fragility, and the time it takes to set up (repeatedly). Basically, the UX of bluetooth is terrible. The UX of a simple, universal, cheap, dependable, quick, robust and high fidelity cable and connector is great.

Whatever tech that will eventually replace the 3.5mm jack isn't here yet.
