Again, I agree that the impact for many people was huge. But there was really no viable alternative. Software was increasingly big, media was becoming big, videogames were big (Doom II was 8 disks I believe), and the first real interactive media was becoming popular (Wing Commander III from 1994 was 4 CD's). Apple ditched the floppy in 1998 (

There was no other way: adapt or die. If in 1998 you weren't ready for the advent of CD-Roms (I think that in 1996 I had my first Blueray, which was Mars Attacks!) you were way behind the times. By then the actual raison d'etre of a floppy disk had became obsolete.
As for headphones, the raison d'etre is audio. I read conflicting arguments, but one thing is certain: there is no way that a good bluetooth audio device will surpass in audio quality an equally good wired device. At most, they will be identical. Therefore, the raison d'etre of wired headphones is not obsolete and won't be for a while. Now, we can find in the lack of wires a good reason for BT headphones. Again, I give you that not having wires for most people is a nice comfort and something with some value. But it's definitely not courage and not a reason for removing headphone jacks, until at least the BT solution is ready for prime time and at an affordable price. It's a much different story than Floppy drives.
