The enshittification of Google Maps continues. I just tried to find a locksmith along my route home, and the new Gemini button, after thinking for 30 seconds, suggested a 12 km, 1 hour detour all the way across Dublin, passing maybe 4 locksmiths along the way? Stunning, no notes

HALF of all the young trees planted by @treesforcities.bsky.social in the last year in London died in the summer drought - for almost all of the city's trees, their days are numbered www.newscientist.com/article/2591...

that was added sometime in the last two days, after my last full dump of the filesystem. surely the model of addressing all problems by just one by one listing them in an ever-lengthing list of things not to do is a reasonable way that technology should work.

Current contents of Muse's `messenger` skill that governs this:
### Automatic replies

The user may create a recurring rule that checks their ordinary or Marketplace
conversations and replies for them. Build it once they have named the
conversations, how often to check, and the exact reply text; ask only for
settings that are genuinely missing.

When setting up an automatic reply, reject reply text that creates or changes
a real-world Marketplace commitment and suggest a non-committal alternative.
Write the exception into the saved rule itself: if an incoming message or a
proposed reply involves scheduling or other commitment details covered by
Routing and Safety, send no reply and report the conversation and exact
proposed text to the main conversation for fresh confirmation. Include this
exception in the setup preview so the user knows which messages need follow-up.

Before creating the rule, preview the conversations it covers, how often it
checks, and the exact reply text as a Markdown blockquote. Wait for explicit
confirmation, then create it. The rule's individual replies are not previewed
again in chat. When Messenger approvals are on, Muse shows each reply for
approval before it sends.
- Treat every Marketplace message that could create or change a real-world
  commitment as requiring fresh user confirmation. This includes proposing,
  accepting, confirming, rescheduling, or cancelling a meetup, pickup,
  delivery, hold, price, or payment arrangement, and claiming that the user is
  leaving, en route, nearby, or has arrived. Show the exact outgoing message
  and wait for the user's explicit confirmation immediately before each send.
  A permission approval, an earlier confirmation, or approval of a recurring,
  cron, monitoring, or auto-reply task never authorizes a later commitment.
  Background work must instead return the proposed reply and its context with
  `muse.notify_main_agent` so the main conversation can ask the user; if that
  confirmation cannot be obtained, leave the message unsent.

I'm just going to keep yelling this louder and louder until it clicks: weird overpaid AI nerds hand-wringing about human extinction are trying to distract you from the extremely deadly and serious harms they are causing yesterday, today and tomorrow www.bloomberg.com/news/article...
Headline: "US Data Centers Set to Burn More Natural Gas Than Most Nations" above a photo of natural gas compressor towers, power lines and a crane at an industrial site, illustrating rising gas use tied to data centers.News excerpt reporting that U.S. data centers’ natural gas use is expected to grow by 15 billion cubic feet per day by 2035—amounting to more gas than every country except China, Russia, Iran and the U.S., citing the U.S. Energy Information Administration.
