Not a single perspective here from someone who didn’t write the report. This isn’t journalism, it’s an author’s abstract. Every para is just “this is what the paper says.” It’s exactly what you would get if you asked an undergrad to read it and write a summary. Or get one from a chatbot.

But, as an archivist, I must say that we are not just throwing our hands up and wailing about it. As a profession we are getting on with finding methods and systems so that digital records do endure. And it’s a little dispiriting when the media periodically repeats the ‘Digital Dark Age’ story.

Honestly, trying to read about AI is exhausting. Always need to know who the author is, what their motives are (often opaque), how much they actually know, what assumptions they make (omg we so badly need some common analytical framing)… Spend more time checking out the author than actually reading

Impact
Alt text: A six-panel comic about a small white ghost haunting a table lamp. The ghost says, “I’m the ghost of this lamp. Just this lamp.” It reflects that it could have haunted “something bigger. A room. A house,” but chooses to “focus my craft” where its impact is “small but does not go unnoticed.” The lamp suddenly clicks on by itself. In the next panel, a confused man asks, “Who turned on this lamp?” while the ghost peeks out from behind the table. The final panel shows the ghost hiding beside the table with a pleased smile as the lamp glows.

Listening to Schubert’s Impromptus, D.935, played by Radu Lupu. This is very beautiful music. Hard to explain, but Schubert somehow mixes events and memories: “let’s dance” -> “remember when we danced”, “let’s talk” -> “remember when we talked” and so on. Schubert had a tender soul.

Waiting for the train to leave Euston back to Birmingham, finding myself in Private Eye (joining in the Radio 3 discourse), mentioning intunemixtapefanclub.dracos.co.uk and coming across as a bit of a nerd 🤣
Radio 3 debate continues...

Sir,
There does exist an oasis of wide-ranging
music, presented with elegant concise commentary. This programme is called
"Through the Night",
At which point the verbal diarrhoea of
from 12:30am to 6:30am.
"Breakfast on 3" takes over with its ten-minute (at best) snatches of music.
DES HILL, London.

...I maintain an archive of Radio 3's
Classical Mixtape track listings going back to
2017. At least there, output seems pretty varied with the number of distinct composers ranging from 481 in 2018 to 599 in 2022 to 478 last year, with around 60 percent of composers having only one track in the whole year.
Radio 3 "Breakfast" is a much nicer thing to
wake up to than the alternatives, and anecdotally I still hear a wide array of known and unknown pieces (this morning included Mozart, Lully, Smyth, Respighi).
MATTHEW SOMERVILLE.

...In all this talk of classical bangers and anodyne presenters on Radio 3, not one mention of programmes like Private Passions or Round about Midnight. Nor indeed the week given over recently to Miles Davis as Composer of the Week.
These were all outstanding and were presented by people with a passion. Anodyne my arse.
