Read my post. I did not compare the two. I was speaking of the progression of technology.
Sure, your post says:
I got rid of my floppy discs years ago, and haven't looked back.
...and you go in to describe jacks as a "security blanket" (i.e. something of purely psychological comfort value).
...in a thread about the removal of 3.5mm jacks.
Sure looks like you were drawing a comparison.
I was speaking of the progression of technology.
...generalisation without warrant is still a fallacy. If you want to make that comparison (and if you post X in a thread about Y then yes, you're implicitly making a comparison) then you need to explain how removing audio jacks is an example of the progression of technology.
=========
Going back to the general issue, progression of technology ain't what it used to be: when floppy discs were falling from their peak, personal computer technology was still progressing rapidly, and the inconvenience of giving up an established tech was countered by the fact that the new tech was (a) an order of magnitude more powerful and (b) often substantially cheaper (if only by inflation). Now, the technology is maturing, progress has slowed*, 5-10 year old devices are still useful and the market is saturated. A shakedown of the market is looming. Progression is too often taking the form of juggling things around and putting form ahead of function in order to generate interest. Technically, Lightning headphones give you a nicer connector (although you have to admit that the 3.5" jack is infinitely rotate-able c.f. Lightning's one degree of reversibility) and re-locate the DAC to the headphones. USB-C is just, again, a, nicer connector that combines several pre-existing protocols.
*Sit an early 2011 MacBook Pro alongside a "comparable" (in terms of position in the range) model bought in 2018. Isn't the new one a nice, slimmed down version of the same thing - maybe 50% or so faster, too... Now imagine an original Apple Mac sat alongside an Apple II system. Best you can say is that they've both got a screen and a keyboard... The Mac totally changed the game both in terms of computing power, and in how the user could use that power. Yet those two systems are also only 7 years apart...
(NB: Note how I'm comparing one personal computer with another personal computer and not, say, the evolution of the RS232 serial port with that of the 5.25" floppy disc drive).
