How is there a parallel to the headphone jack?
Flash drives were first released in 2000.
So... were “better alternatives” available? Yes. Were they incorporated onto the machine? No.
The idea was that almost all output would occur through the network, and that was a fairly prescient idea. If you wanted writable media, you had to add it externally — via a USB 1.1 connection, if memory serves (though maybe the machine also had a FireWire port, I can’t quite remember).
The point was that the floppy drive wasn’t removed because they replaced it with “better alternatives” on the machine, the point was that they thought that obsolete media had no place on modern almost-turn-of-the-millennium platforms.
I’d argue that there’s a pretty good parallel here.
(This wouldn't have taken very long, however, unlike the headphone jack, which is likely to remain the superior audio connector for consumers longer than the iPhone remains a product.)
While I'm not an expert on cars, most cars that have keyless entry that I've came across DO come with physical key, either separately, hidden inside the key fob, or the whole key fob works as a physical key as well. The only exception I know of is Tesla, but even they give you 2 keycards and you can purchase more. The reason is basically the same the reason I want headphone jacks back - fobs/Bluetooth can run out of battery, they are expansive to replace so you can't have multiple of them lying around.
While I do use the wireless option most of the time. I want the wired option as a backup.
Additionally, wired better functionality than the wireless option in this case - FM radio (not relevant for iPhones, but it does for Android), better audio quality, less battery consumption, ability to charge the phone while in use - features I personally am not very attached to but can see why they might be important for other people.
