This makes me wonder what methods of transferring information we may have lost historically that we don't even recognize?

Will there be analog clocks in 30 years? It seems somewhat doubtful, particularly if this generation can't read them.

What benefit is there to keep this antiquated method around, aside from just as an historical reference?

I'm in my 50s, so I can read an analog clock, and I have analog watches. But I don't feel the need to force this method of time on future generations.

Digital clocks are not subject to the drift that analog clocks are, they don't require the user to learn to read them, and if they are broken, it is fairly obvious at first glance.

What benefit does an analog clock have, aside from that it can work without power? And even then, it's only those that are purely mechanical, which I think is also dying out.
