The real value isn't in getting it at the time, it's having those seeds planted, among a population who will likely read very little after graduation, to find fertile ground later.

There's all manner of things I'd Studied in School (primary, secondary, uni) which only became clear to me many, many decades later.

I'm helping an older friend with their one remaining pastime, audiobooks, many of which are re-readings of works they'd first encountered as a teen or young adult (now in their 10th decade). As TFA notes, there's a thickness to many of these works, and even having read them several times already, there's a reward in hearing them again, 60 or 70 years after first encountering them.

I listen in on some of the books. They've covered over 2,000 titles, which is impressive for anyone. One aspect that stands out to me is that I now catch the references to many of them: Herman Hesse commenting on Dante Gabriel Rosetti's "Beata Beatrix" (at the Tate), several references to Erewhon, and numerous places, people, and historical events of which I now have far more context.
