I suppose the modern successor to the 5 1/4" floppy is the USB flash drive, which can hold a jillion times more data, is a jillion times faster, is smaller, and is more durable. You'd have to be a complete idiot to prefer the former.
Can we honestly say that Face ID is much better than Touch ID? ... Actually, is it any better at all?
I've never owned a phone with Face ID but I'm constantly seeing people around me being forced to enter their PINs because Face ID has failed in whatever particular situation they were trying to use it in.
While I can go for weeks without having to enter my phone password with Touch ID...
Anecdotes are all well and good -- but past a certain point, they are all highly subject to interpretation.
You say you are "constantly" observing people who have issues with Face ID. (I would be tempted to question that assertion -- but let's take it at face value, for the sake of conversation.) Thing is...
I've gone for weeks without any issues with Face ID. Does that somehow make me better at technology than the people who you've observed? Of course not. It's an anecdote. It means only that one person's personal observations are different from another's.
Paralleling that, you also observe that you can go for weeks without an issue with Touch ID. Well, I had an iPhone 6 with Touch ID before I bought an iPhone X with Face ID, and I've had multiple iPads with Touch ID. It worked well enough most of the time, but it was by no means perfect. I know all too well the struggle that Touch ID can present when it decides for one reason or another that it just doesn't want to play. I am also all too familiar with that annoying initial task of training it to recognize a fingerprint in the first place. Do my past struggles somehow make
you better at technology than me? Once again, of course not. It's an anecdote.
The point is, what matters most isn't necessarily the details surrounding our anecdotes. It's the overall trends surrounding them. People migrate to newer technologies, over time. That's just a thing. You can like it or dislike it and you can complain or celebrate it -- but there's really not much you can do to
stop it.
Me, I'd rather be the guy figuring out how to bend that new technology to my will. Oh, I'm sure I'll complain now and again, along the way, while I work my way up the learning curve... but it's a matter of mindset: I just think it's more interesting to complain about
new toys than it is to complain about not being able to
find those old toys that I used to enjoy playing with.
(Poor old codger... I really did feel sorry for him. But the fact was, nobody
sold systems with 5 1/4" drives, anymore. You just
have to move on, at some point.)
