I've seen quite a steer in my timeline: ~1-2 weeks ago in English, in June/July in German
My 2ct:
1) "antiquarian" is misleading; we're talking about books with ISBNs, which means >1970
2) Quoting myself:
"It's a small difference, but imho an important one:
Anthropic (and Meta) uses existing industries for their operations, they do not build them from the ground up."
