We need high-speed rail everywhere. Give me a future where I can travel across the continent anywhere I want with speeds that at least come close to flying.
It's easier to make trains carbon-neutral. I'd rather watch all the scenery go by. Let's do this.

Maybe this will lead to a golden "take Amtrak instead of flying" era

Breaking: we release a fully synthetic generalist dataset for pretraining, SYNTH and two new SOTA reasoning models exclusively trained on it. Despite having seen only 200 billion tokens, Baguettotron is currently best-in-class in its size range. pleias.fr/blog/blogsyn...

Part of the reason why I’m so insistent about folks understanding AI capabilities is that they’re here to stay and we need to start thinking about what to do in such a world. Putting the genie back in the bottle is a pleasant fantasy that delays serious reckoning

It is good for humanity if ai is spread out across all these great companies
The DeepSeek moment underestimated the talent portion & overfocused on training capital in N of GPUs.
The rest of 2025 has been living through that reality with Kimi, GLM, Ant Ling, Meituan... The burden of proof is back on scaling if AI will be in the hands of a few companies.

When we ask an LLM to “reason” about an ethical question, what kind of reasoning are we really invoking? Our #EMNLP2025 paper with Mohna Chakraborty and Lu Wang explores how value-grounded prompting can move moral reasoning beyond surface pattern-matching.

This is yet another example of how you beat the far right. By beating them, not trying to be them. By having your own agenda, not aping theirs. With courage and conviction - and humour - not fear and timidity.

This. Copyright is a tool for protection but it’s not everything. In fact, there’s research showing that it is possible to create competitive language models using public domain data only. The proliferation of copyright respecting models would not solve the labor impact policy problem.
Imagine you time travel back to 1847 and you find the left response to industrialization is a) machines will never be as good as human weavers or b) we need to copyright loom patterns or c) it’s a speculative bubble.
You’d say “Y’all. Not helping. What you need is obviously a labor movement.”

More than technology or any physical structure, i do believe that government structure in the west needs to change so that people can try things for the benefit of the people like this. We could have so much more transit if it wasn't so hilariously expensive to build
Smart tram in Zhuzhou, China. Follows markings on the road, so construction costs are way lower. Basically bus rapid transit but with the option for huge buses.
