Other, less difficult media

While rummaging through my shelves, I came across a poem from the 1950s that seems strangely apropos to current debates about the future of the book, or its possible lack of one: "To Posterity," by Louis MacNeice:

When books have all seized up like the books in graveyards
And reading and even speaking have been replaced
By other, less difficult, media, we wonder if you
Will find in flowers and fruit the same colour and taste
They held for us for whom they were framed in words,
And will your grass be green, your sky be blue,
Or will your birds be always wingless birds?

I now also see, thanks to the online equivalent of rummaging, that MacNeice's letters will be published in a couple of weeks.
