Claude is the best editor/critic of blog posts, emails, or essays. It’s brutally honest.
I prefer to do my own writing, but I constantly ask Claude to review the text over and over, often 5-7 times. The feedback I get is phenomenal, and the prompts couldn't be any simpler.

I started an email reply with “You’re absolutely right,” and the person was sure it was an AI responding. Speaking like AI is the new “life imitating art.” Maybe I should put Claude Code down for a while. 🙃

AI won't take our humanity because our humanity is about other humans. 2026 is the year we rebuild what we lost.

We are about to witness unprecedented levels of psyops, disinfo campaigns, and astroturfing. Society is not prepared for this, and social media companies benefit from the engagement, so they won't do much to stop it.

If true, this will be the inflection point for EV cars. A battery that delivers 30-60% more autonomy, charges in 5 minutes, lasts longer than the car, and it works under cold/hot temperatures. insideevs.com/news/783380/...

I'm looking for a designer (a person, not an agency) to help with a basic branding and website design for a project, probably 20-30h of work. When I lived in London I was impressed by the quality of the UX/Brand designers there. Is there a site that can help me find a person for this job?

Mega VC rounds are skewing the data about the realities of startup investing today. 2026 will be a hell of a year for early-stage startups to raise money.

The React/NextJS vulnerabilities recently discovered are a great example of how we still depend on software engineers. What happens to the vibe-coded apps deployed by non-engineers? Tech is too fragmented and too diverse for us to develop a unified AI agent to handle this.

This is closer to the true cost of AI models, in which case the tradeoff between AI and human labor blurs. For comparison, $168/day is more than the minimum wage is most places.

To add insult to injury, now LinkedIn is hiding comments with links from the post author!
LinkedIn/Twitter/Threads shows posts with links to fewer people. The “standard” became to share the link in the comments so you reach *your* audience and people click the link in the comment.

Stop saying “knowledge worker” to refer to professionals who work from an office. Instead, say “information worker.” Dentists, plumbers, and teachers require substantial knowledge to perform their work.

I've been paying for ChatGPT for over two years, and it represented 99% of my LLM usage until four months ago. Now, 100% of my coding and 90% of my writing have shifted to Claude, and 50% of my research has shifted to Gemini. I still use ChatGPT for lifestyle questions (cooking, travel, finance...)

Twice last week I've seen founders proudly announce their new startup by telling people how hard they'd been working on it without explaining what they do, what problem it solves, or who it's for.

2005: Approved by FDA for diabetes
2014: Approved for weight loss
2025: Recommended by the WHO
