Expecting researcher taste and judgement to become increasingly valuable (this is from Anthropic's Opus 5.5 system card) anthropic.com/claude-opus-...
This is highly uncertain, but we expect that full automation of AI R&D
will require large improvements in foresight, prediction, creating
one’s own feedback loops, and generally other skills that might
typically be referred to as researcher “judgement” or “taste”.
○ The evidence we have does not suggest that [Claude Opus 5.5]
represents a large improvement over Fable 5.1 in these
“judgement” skills.

Despite a growing demand for causal evidence about social media, independent researchers remain severely
constrained in their ability to conduct experiments directly on online platforms. To cope, multiple method-
ological workarounds have emerged—from controlled surveys and simulations to client-side overlays and
platform partnerships—each requiring distinct trade-offs between desirable experimental properties. The
recent emergence of open social media platforms offers a qualitatively different methodological opportunity.
Here we propose a design space of social media experimentation and discuss Open Platform Field Experiments
(OPFEs). OPFEs represent a distinct class of experimental approaches that enable independent researchers
to directly intervene on functional platform components—such as clients, recommendation systems, and
moderation services—within live social media environments. Through a comparative analysis of experimental
archetypes, we show that OPFEs occupy a previously unexplored region of the design space. We then bridge
theory and practice by characterizing the architectural and governance elements that enable OPFEs, mapping
them onto Bluesky and the AT Protocol, and illustrating the end-to-end lifecycle of a complete OPFE design.
Overall, this work establishes OPFEs as a practical methodol…

"banality of ignorance: the willful suspension of judgment that allows people to see suffering without confronting it and to hear lies without rejecting them. The monster does not merely demand obedience. It needs subjects who have learned not to think about what their obedience makes possible."
counterpunch.org
When Monsters Walk Among Us
More than four decades ago, the Greek composer and public intellectual Manos Hadjidakis issued a warning that now reads less like a reflection on fascism than a prophecy of our own time. The greatest danger, he suggested, comes when we grow accustomed to the monster, when its presence no longer shocks the conscience and its violence begins to merge with the routines of everyday life. Tolerance does not diminish the monster; it multiplies the conditions that allow it to flourish, strengthening its presence in public life until monstrosity itself acquires the authority to govern. In this instance, the collapse of conscience is inseparable from the uncoupling of “belief from judgment, conviction from action.”

Shipped a new thing on @airglow.run: social graph sync 🔄 Pick the apps you use (Bluesky, @tangled.org, @sifa.id, @grain.social, @semble.so), turn it on, and your follows stay identical everywhere. Follow someone on one app, you follow them on the others too
Airglow's social graph sync page for @there-hugo.dev. Under "Apps to keep in sync", five apps with checkboxes and follow counts: Bluesky 192 follows (on), Semble 75 (off), Sifa 57 (on), Tangled 121 (on), Grain 63 (on). A note says removing an app or turning sync off never unfollows anyone. A Status section shows five cards: Sync "In sync", Queued "0 changes", Waiting on Grain "129 people", Waiting on Sifa "135 people", Waiting on Tangled "71 people", each explaining those people are followed as soon as they create a profile there. An Activity list shows recent entries such as "Followed on Grain" and "Skipped on Grain, no profile yet, waiting for them to join".
