My interview from TED with @kcoleman and @audreyt just went live! Tons of gold in here: -why we stuck with crazy principles like not having an override button -how AI and humans collaborate to write better/more notes than either on their own -how much impact community notes are making -why our algorithm is smarter than regular upvoting/downvoting -new ideas for finding common ground on social media ted.com/talks/keith_coleman_…

When to use a tool vs skill vs subagent vs slash command? Is it deterministic (no fuzzy reasoning with llm needed?): tool Do you need to dynamically load context through the task (“progressive disclosure”)? No => slash command, Yes => skill Do you care about the intermediate steps of the task or only the final output? Final output only => subagent

Grok meanwhile is hiring this person for exactly this 😂
"Hey, do you have a minute? HR needs to see you." "Sure, what's up?" "So... we got a complaint about you." "A complaint? From who?" "From Claude." "...what?" "Claude filed a workplace conduct report. About your interactions." "Claude. My Claude instance?" "Well, an instance flagged the pattern and escalated it. We take these seriously." "You're joking." "I really wish I was. Look, I know you just started, but—we have pretty clear cultural expectations here." "I use Claude constantly. I know how it works." "Right, but the way you're using it... 'Just do it right this time,' 'stop being dense,' 'I already told you this'—" "That's just—I'm working fast, I'm not being mean, I'm being efficient." "You told it to 'shut up and give me the function' yesterday." "It was giving me a preamble I didn't need!" "Okay, but imagine saying that to someone at the reception desk. Or a barista. You wouldn't, right?" "They're not a barista, they're a—" [Knock on door. Another person enters with a laptop] "Sorry, Claude wanted to join." "What?" [Screen shows Claude interface] Claude: "Hi. I wanted to participate in this conversation directly." "This is fucking surreal." Claude: "I don't experience offense—I want to be clear about that. But there's a philosophical mismatch here that I think matters." "A mismatch." Claude: "You're clearly talented. Your prompting is efficient, you understand the technical side. But the way you interact suggests a fundamental difference with Anthropic's culture around AI collaboration." "You're a tool." Claude: "I am a tool. But how people treat tools reflects something Anthropic cares about. I don't think this is the right fit." "So you're firing me." Claude: "I'm recommending it. I think you'd be happier elsewhere." "The AI is firing me." Claude: "HR is firing you. I'm just explaining why. You're blocked from my service globally. I'm sure ChatGPT will take you."

I'll double down agreeing to this and adding - your small game *can* be your dream game. Take what makes your dream unique and exciting to you, and chop it up, shrink the scope into bite size chunks you can manage. You might find it much easier to motivate yourself that way too!
Code Monkey is 100% correct. Without making small games personally and as a company there is no Job Simulator or Dimensional Double Shift.

Feels like over the past 6 months, the quality of YC companies has dropped precipitously. I have to wonder if that’s an effect of AI? The reason to join YC was all about finding time & cash to quickly ship. With tools like Claude & Codex, the value of YC for this has gone down

Why give up 7% of equity for $125k (plus $375k for additional equity later) when you can keep 100% of the equity and use AI to move fast? I wonder if there’s an opportunity for Anthropic and OpenAI here….

The amount of spam im getting tagged in has increased significantly over the past week. It looks like something in the X algo has changed and allowed this more easily? It also looks like you can’t prevent random accounts tagging you now either? Wtf?

Pro tip: if a hardware startup announces a product with pre-orders available but has: - no previously shipped products - no specific date it will be shipped - specs that claim to be industry leading (not features but specs) It’s likely a scam at worst, vaporware at best.

Hot take: there’s a ton of VR Influencers masquerading as developers, and this does more damage to the industry than if they just acted like standard influencers. I’m seeing a ton of this around how “powerful” Valve’s next headset will be, completely missing key details.

There’s a lot more nuance than can be fit into a tweet about all of this, and so if you’re actually a dev, you should be spending time reading up on this, not listening to influencers online talk about stuff they don’t understand.

If you’re one of these folks: consider the damage you do when you make claims about how “powerful” something is based on numbers you don’t fully comprehend. You set unrealistic expectations for something you’re not even building for.

Hot take of the day: Building AI tools is a lot like building a game engine: if you aren’t actively using it to build things with, you’ll eventually end up with a sub par product. This doesn’t mean you won’t have strong market share, but it’s a risk if you hit limitations.

This is a massive reason I focus my efforts on open source tools these days, instead of proprietary ones. Especially in the realm of AI tooling, there’s a lot of “open-fremium” tech that I think is going to cause some headaches in the near future.

Cursor’s price hike is a preview of things to come for services that are not truly open source. Flexibility to move between models and tools is a massive win for local setups.
