New paper in Nature. The more a government controls its domestic media, the more it dominates AI training data, the more pro-regime outputs we get from AI. By scraping the open web, LLMs are unwittingly laundering state-coordinated narratives into seemingly objective answers.

Nothing much new here as far as I can see, the EU and CPTPP countries already have lots of overlapping trade agreements and intend to keep them. Not much of a response to the biggest emerging danger which is the largest powers (including the EU) weaponising supplies.

How's this for energy abundance? Millions of Aussies will start receiving three hours of free power each day in 2026. This is what happens when you make rooftop solar less than a buck a watt!! "Rooftop solar installations cost about $840 (U.S.) per kilowatt of capacity before rebates." 🤯 🔌💡
For years, Australians have been been installing solar panels at a rapid clip. Now that investment is paying off. 

The Australian government announced this week that electricity customers in three states will get free electricity for up to three hours per day starting in July 2026. The Solar Sharer plan will be available to everyone in New South Wales, South Australia, and in the southeastern part of Queensland to start; more regions will be added later. Households won’t need to have solar on their rooftops to qualify, though they will need a smart meter installed. The plan will help those who live in apartments or don’t have a suitable rooftop to benefit from their neighbors’ panels, Bowen said.

Although the government hasn’t said which hours in the middle of the day will qualify, the hours between 11 a.m. and 2 p.m. are the most likely candidates. Customers will have to opt in to the new plan, which is meant to encourage people to shift their energy use to peak solar-production hours. Smart appliances can help people make the most of this by allowing them to time charging their EVs or running loads of laundry.
