OK so I'm not gonna derail the Metafilter thread about this, which means I'll complain about it here:
Someone quoted Stewart Brand's story about old oak beams in New College, Oxford having replacements planted specifically for them 400 years ago.
I said it's not true, as per the college's archivist.
Another person says I'm wrong. Interesting! Has some new evidence been revealed, like records dating to the time in question? https://www.metafilter.com/203640/How-Kings-College-Added-438-Solar-Panels-to-a-500-Year-Old-Chapel
