Judging by how everything is going, we’ve mastered social behavior and can move on to more solvable problems.
The NSF 2027 budget has noted that they will close out the Social, Behavioral, and Economic Science Program (SBE). This is not a good thing. nsf-gov-resources.nsf.gov/files/FY-202...

This seems to me to capture *everything* about coding with agentic AI: “A lot of the work is right-sizing tasks such that they’re big enough to be genuinely useful compared writing the code yourself, but small enough that the model can complete it (ideally before compaction).”
"No sense of time" also applies to being very eager to write lots of code; most people would feel that a change that's getting too large / taking too long, take a step back and rethink the approach.

You can vibe code your way to a working prototype. You cannot vibe code or one-shot your way to a competitive product that works at scale. The hard part isn't writing code; it's the architectural supervision.

Anyway, if you are still writing and understanding your own code in 2026, you have my deepest appreciation & gratitude.

Thoughts from a newbie using Claude Code for the first time.
I don’t always use GitHub for my projects, but with Claude Code it feels like a must. Having a tool read and write files without version control is just too scary.

I can’t wait to watch these! Knowing Andy, they’re going to be great.
I just created a series of seven deep-dive videos about AI, which I've posted to youtube and now here. 😊
Targeted to laypeople, they explore how LLMs work, what they can do, and what impacts they have on learning, well-being, disinformation, the workplace, the economy, and the environment.

I've never seen a population more united. If people can hold onto that unity, if people can accept that different people will have different ways of confronting fascism, if we can remind NGOs and orgs that they can join but not control the resistance, then, well, people here will write history.

But when I asked an organizer what they wanted to see out of press coverage, they told me they wanted people to see the beautiful things they are building here, and not just the worst stories of the worst of ICE's crimes.

It’s notable that the president can go on TV and be a total gutter racist, and somehow this isn’t news in the slightest. Says a lot about the sickness of American society right now.
Trump: "They're paid agitators and insurrectionists. Nobody talks about the fact that $19 billion at a minimum is missing in Minnesota, given to a large degree by Somalians. They've taken it. Somalians. A lot of very low IQ people."

US trade secretary Howard Lutnick really not mincing his words here at Davos: "We are here to make a v clear point: globalisation has failed the West and the USA. It's a failed policy. It's what the WEF has stood for, which is, export, offshore, find the cheapest labour in the world."

Even the cosmologists expected this
Literally everyone who even vaguely knew what a tariff was said this when they were introduced! You don’t need a team of economists to analyze the situation — no one who lives in reality was confused by this!
“Foreign exporters absorbed only 4% of last year’s U.S. tariff increases by lowering prices, while American consumers and importers absorbed 96%.
“Rather than acting as a tax on foreign producers, the tariffs functioned as a consumption tax on Americans.”
