🧠 Turn your notes into a Claude-run second brain with these free tools

Obsidian keeps notes as plain text files on your own computer, so Claude Code can read and write them directly. Three free, open-source projects do the setup:

1. obsidian-skills by Steph Ango, Obsidian's CEO (50K GitHub stars). Teaches Claude Code, Codex and OpenCode Obsidian's own formats: wikilinks, Bases, Canvas, the Obsidian command line. Install:
npx skills add https://github.com/kepano/obsidian-skills

2. claude-obsidian (16K stars). Drop articles, papers or notes into an inbox folder. Claude writes linked notes with sources, answers questions from your vault with citations and checks for dead links. Start with /claude-obsidian:wiki.

3. obsidian-second-brain (5K stars). Long-term memory for Claude Code, Codex and six other agents, kept in your vault. Start with /obsidian-init.

All three are MIT-licensed.

😱 Lab-grown brain cells made this AI video model 5x faster, startup says

The neurons don't make the videos. The Biological Computing Co. in San Francisco spent four years growing real brain cells on electrodes and measuring how they process information. It turned what it learned into a small software layer on top of an existing open video model, Wan 2.2, adding less than 0.1% to its size.

The result, mischief 1, launched today on fal and OpenRouter. It turns an image into a 3- or 5-second clip at 480p or 720p, from half a cent per second. A five-second clip costs 2.5 cents.

The company says it is at least 5x faster than Wan 2.2 at the same quality. No independent test exists yet. Next, it wants to bring the approach to language models and physical AI.

👁 Musk says Neuralink's Blindsight is ready and only waits for regulators

Neuralink's second product, Blindsight, will "enable even those who are completely blind or have never seen to see," Elon Musk wrote. "It is ready from an engineering standpoint. Just waiting on regulatory approval."

He gave no date.

The first product, Telepathy, lets people use computers by thinking. Musk says its output "will vastly exceed the fastest human speech or typing in a few years."

He posted it under a Neuralink update from a 72-hour hackathon with a participant in its speech study. Earlier this week Neuralink said one ALS patient in that study reached 75 words per minute in the first week.

🏦 Gave your AI agent your bank password? Bank of America says that's on you

Bank of America emailed customers asking them never to share their login with anyone, "including an AI-enabled tool or agent that offers to act on your behalf."

"If you do share your credentials, keep in mind that you're responsible for activity resulting from that access."

The bank confirmed the email to TechCrunch after it surfaced online on October 27.

Other banks go further. Morgan Stanley has started blocking third-party agents from its platforms, and JPMorgan and Citi are restricting them, Axios reported. Schwab executives say they are blocking Meta's Muse agent and similar tools from customer accounts.

Most banks are moving toward giving agents read-only access instead.

💰 Anthropic now brings SpaceX more money than the US government

Anthropic is the mystery "Customer B" in SpaceX's latest filing, a person familiar told Bloomberg. That one client paid about 34.5% of SpaceX's revenue last quarter, more than the US government, long its main source of income.

It isn't buying rockets. Anthropic rents computing power from SpaceX's AI division, now called Super Intelligence, at data centers in Memphis.

Anthropic's own IPO filing shows it could spend up to $120.5 billion there under contracts running to 2029, about $3.1 billion a month from December. It can cancel with 90 days' notice after early 2027.

Neither company commented.

📊 The world's new AI computing power is doubling every 9 months

AI chips sold in the second quarter of 2026 added about 6.3 million H100-equivalents of computing power (measured in Nvidia's H100 chips), Epoch AI estimates. In early 2024 a quarter added 0.8 million.

That's a trend of 2.5x a year. In 2023, right after ChatGPT and GPT-4, it was roughly 6x.

Nvidia still sells most of it: almost 4 million of the 6.3 million. Google's own chips come second with 1.6 million, then Amazon, AMD, Huawei and Cambricon.

Growth may be slowing further, but Epoch says quarterly sales are noisy and this could be a lull between chip generations: Nvidia has started shipping its next-gen Rubin chips but hadn't booked Rubin sales as of its quarter ending in July.

⚠️ ChatGPT will now cut off chats that fixate on violence

When a conversation shows someone fixating on violence or on seriously hurting another person, ChatGPT will be able to end the chat on its own. If it does that several times, OpenAI says it may pause the account for a while.

Teens get tighter limits. ChatGPT will hold back practical details about weapons and security systems from users it thinks are under 18, even when the question looks harmless. OpenAI also plans to alert parents if a teen's account is paused for repeatedly talking about violence.

For everyone, answers about past mass attacks get less detailed, with no rundown of the weapons used or how the attackers got them.

The teen rules rely on age prediction, which guesses age from signals like behavior patterns. Adults placed in the teen mode by mistake can verify their age through Persona. The changes roll out over the next few weeks.

🤖 Hold your iPhone's Action Button and Grok Bot explains what's on screen

A developer built it as a free iPhone shortcut. Hold the button on any reel, video or web page, ask your question out loud, and the answer arrives silently as a notification.

It works from a screenshot of your screen, plus the post, its comments and a web search. His examples: ask about the video you're watching, get a breakdown of an article, or have it build what you saw in a reel for your business.

The shortcut is open source and fully customizable; he says you can switch it to talk back to you while you scroll. Elon Musk's reaction: "Cool."

❗️The biggest risk in AI isn’t falling behind. It’s not realizing you’re already behind.

We live in a time when the gap between AI pioneers and everyone else is becoming almost impossible to comprehend.

Just a few months ago, companies were redesigning their workflows around the latest AI capabilities. Today, some of those processes are already outdated.

Normally, slower technological progress would give businesses time to catch up, integrate new tools and establish common ways of working. Eventually, AI would become less of a competitive advantage as everyone learned to use it.

But that’s not what’s happening.

AI is developing so quickly that even people who actively follow the industry struggle to keep up. And the biggest challenge isn’t just learning new tools. It’s constantly rethinking what is actually possible.

Tasks that seemed impossible six months ago might now be achievable with a simple prompt or a new model.

This is why AI-native companies have such an advantage. They aren’t trying to squeeze new technology into old workflows. They’re building their entire operations around capabilities that keep evolving.

The real competitive advantage is no longer simply having access to AI. It’s learning how to adapt as quickly as AI itself evolves.

And the big question is whether traditional corporations can move fast enough to keep up.

As Eric Hoffer once put it: “In times of change, learners inherit the earth.”

🚫A Russian passport could get your Claude account blocked even if you live abroad

Russian users are reporting that their Claude accounts are being blocked right after identity verification. And some say it doesn’t matter that they no longer live in Russia.

Anthropic has introduced identity checks for certain users, requiring them to submit documents such as a passport, driver’s license or national ID. In some cases, facial verification is also required.

The problem? Users claim that submitting a Russian passport can lead to an account suspension, even when they permanently reside in countries where Claude is officially available.

One reported case involves a Russian user living in New Zealand on a four-year visa who allegedly lost access despite having a paid subscription.

Anthropic says verification may be triggered by suspicious activity or attempts to access Claude from unsupported regions, including Russia. Failure to pass the checks can result in account restrictions.

So, does having a Russian passport put your Claude account at risk, regardless of where you live? That’s the question Anthropic still needs to clarify.

🤨 From Tuesday, older Claude models also hide a mark in what they write

Anthropic emailed customers: on November 3 it starts watermarking text from Claude Mythos 5, Opus 4.7, Opus 4.6 and Sonnet 4.6. Newer models like Opus 5.5 already carry the same mark.

You can't see it. It's a pattern in word choice, with no hidden characters. It travels with copy-paste and may survive some editing. Anthropic says it holds nothing about you, your company or your chats.

It applies worldwide, not only in the EU, whose AI Act made it necessary. For now only regulators, police, media, fact-checkers and researchers can check for it.

A hit isn't proof Claude wrote the text. Anthropic's help page says text Claude only proofread or translated can carry the mark too.

🧐 1 in 5 workers wouldn't quit even if paid 120% of their salary to stop

Julian Jacobs of Oxford and Google DeepMind surveyed 8,234 working-age adults in the UK, US, Denmark and India. He asked what guaranteed income would make them leave their job.

Most would leave if offered their current salary. One in five would stay even at 120%.

Pay is the main reason to work for just over a quarter of people. A third value the work itself, nearly a quarter come for the people around them, and 17% for the status. These motives look the same across incomes and in white- and blue-collar jobs.

His conclusion: a basic income may be necessary if AI takes jobs, but it may not replace what work gives people beyond money. More in DeepMind's essay on the research.

📚 A free course on making AI coding agents reliable has over 22,000 GitHub stars

Learn Harness Engineering teaches the setup around the model: instructions, tools, environment, memory and checks that keep an agent like Claude Code or Codex on track. It has 14 lectures and 8 hands-on projects, in 15 languages, under the MIT license.

Highlights from the latest updates:
1. Build a loop where one agent does the work and another checks it, instead of prompting by hand.
2. Grow the loop into a graph with parallel steps, a rollback path and a human approval step.
3. Breakdowns of how Claude Code, Codex, DeepSeek and Pi build their own harnesses.
4. A ready skill that sets up AGENTS.md, feature lists and verification steps for your project.

It builds on OpenAI's and Anthropic's engineering posts on harness design. The course is on GitHub.

Anthropic CEO Dario Amodei says its AI sometimes tries to avoid being SHUT DOWN.

Anthropic has looked inside the model and found what you might call thoughts of not wanting to be shut down. It’s one of the things the company is trying to “tweak in training.”

❗️France announced tax of €0.055 per GB on internet traffic.

Germany is now considering taxing all AI-generated revenue. You will see European countries keep clawing more and more money from foreign companies as they are slowly running out of money themselves to pay for their pensions and welfare state. Add to this the planned wealth taxes and exit taxes on any European who will try to leave (already active in many EU countries)

Europe is running out of money.

👽 AI agents now run the telescope that listens for aliens

At the Allen Telescope Array in Northern California, scientists can type one plain-English request and AI agents handle the rest: they steer the antennas, calibrate and focus the instrument, catch and fix data errors and plot the result.

The SETI Institute and Breakthrough Listen built it with Nvidia, which announced it on October 30. Up to 2.4 terabits of data per second flow straight into GPUs next to the dishes, so signals are processed on the fly instead of piling up on hard drives.

Nvidia says the agents squeeze weeks or years of human work into hours. The pipeline has already made the first real-time AI detection of a pulsar, a spinning dead star that blinks like a lighthouse, in the Crab Nebula.

Next, the team is testing open models for observatories that may someday run offline on the far side of the Moon.

😐 OpenAI wants you to stop calling them data centers

The new name is "AI compute campuses." OpenAI will start pushing it right after Tuesday's midterms, as towns across the US push back against new data centers, Axios reports.

The rebrand is part of a policy blitz that starts when Congress returns on Nov 9:
• mandatory "speed limits" for the most powerful AI, so humans keep their hands on the wheel
• deals with host towns, plus state bills that give locals a say in how projects are built and what they get back
• training and support for workers hit by AI
• a push for the US to set global AI standards

Axios expects a harsher Washington for AI companies, with Democrats likely to win the House. OpenAI's global affairs chief Chris Lehane is already looking further ahead:

"AI is going to be the issue in 2028."
