Patrick Skinner - edu/acc

For those who are interested in working in EdTech, I need to be honest with you about what you're signing up for. You probably shouldn't apply. EdTech's graveyard is full of brilliant engineers. AltSchool raised $200M and closed. Knewton raised $180M and sold for scraps. 2,148 edtech startups in India shut down in the past five years. They didn't fail because of a lack of technical skill. They failed from mission drift. Here's what working in edtech actually means: You're not building software. You're building a theory of how children learn. - @MitchForest When you're 2 months into the same feature, and it still doesn't work, you won't have the dopamine hits of shipping fast. You'll need something deeper. For the engineers who build learning apps for @AlphaSchoolATX, they are REQUIRED to spend 2 hours every day studying. Not coding. Studying and reading papers on cognitive load theory, motivation research, and translating learning science into applications. Two hours. Every single day. Engineers like @yiran__c write about the neuroscience of handwriting. @arpangup shares the Harada Method. @LamarDealMaker explores AI for skill development. This isn't optional. It's the job. Your success metrics will lie to you. High DAUs don't mean kids are learning. Viral engagement doesn't mean mastery. The metrics that drive consumer tech success actively undermine educational outcomes. The money will tempt you to build the wrong thing. EdTech market: $400B by 2030. That capital creates pressure to optimize for pitch decks instead of classrooms. Byju's hit $22B before collapsing. An MBA analyzes constraints. A builder changes reality. What we require: ➡️ Mission Alignment ➡️ Agency ➡️ Strong Engineering Skills If you're chasing market opportunity or building for your resume, don't apply. But if you're a builder who sees broken systems and feels an overwhelming need to fix them? If you believe high standards create happy kids? If you want to change education for a billion children? Before applying, read the link in the reply. And if you're still interested after understanding what it really takes, let's talk about joining us in building the future of EdTech.

Check out the apps used at Alpha School! Our cursive handwriting app is rolling out to Alpha Schools right now. Would you be interested in trying it out?

Am I so early that we're now just repackaging agentic workflows and renaming them? Isn't this just Ralph Wiggum as a slash command?

@nikitabier I'm so excited for this! My bookmarks are currently a disaster.

Today we're rolling out a new History tab on iOS to help you keep track of all your favorite content on X. Bookmarks, Long Videos, Articles and Likes will live here -- so you can always come back and continue watching or reading. The Timeline moves fast, so we hope this creates a better place for catching up on long-form content.

Hey @Superbuilders... do I really look like this when I'm thinking? if so... I'm ngmi

There's no better time to be one of those types who think, "fine... I'll do it myself," and can lock in for a few weeks to make moves.

Any time there’s a “flat org chart” and it actually works it’s because the entire company reports directly to one god-emperor who makes 999 decisions/day

AI increases output. But the real challenge is direction, clarity, and execution. In Session 3, @PSkinnerTech explores how to become a more effective builder in the age of AI, and what systems, workflows, and processes make that possible.

Cursive is quietly making a comeback. Common Core killed it in 2010. 16 years later, half the country is bringing it back.

@steipete This solves a direct problem I'm dealing with. FYI, your website codex(dot)bar kicks back an error.

🎚️ CodexBar 0.25 is live 🧩 New providers: Manus, MiMo, Qwen, Doubao, Venice + more 🔔 Quota warning notifications 👥 Stacked Codex account switchers 📊 Faster cost history via models.dev Big one. Menu bar still tiny. github.com/steipete/Codex…

@AAlnseirat @gauntletai Turning your brother into an ngmi ad is savage.

Life update: Two years after high school, my twin just graduated with a BS in BCIS… and the same week my portfolio hit six figures. He got a whole lot of BS. I got a whole lot of $$$. How? @gauntletai

Geoffrey Hinton, Godfather of AI, on Alpha School: "we already know that a private tutor is about twice as efficient as a classroom" "and AI (tutors) should be much more efficient than that" "which leaves more time for the socialization aspect of education where you do want to interact with the people and have team projects and things" "That seems very good to me."

@eladgil I’m sitting here wondering how far back is in Austin are. I can’t imagine NY is anywhere ahead of us.

@kutluokan I dunno who I’m more triggered by. You for writing this or the person that thought this was worth bookmarking.

me trying to get the latest from @PSkinnerTech

@claudeai @SpaceX Waiting for @elonmusk to weigh in on this...

We’ve agreed to a partnership with @SpaceX that will substantially increase our compute capacity. This, along with our other recent compute deals, means that we’ve been able to increase our usage limits for Claude Code and the Claude API.

Your child will learn from an app built by a student - or they will build one themselves.

I'm surprised nobody talks about this movie.

@MrZachG So excited to have our kiddos going to school together!

I'm excited to announce that my daughter will be attending Matt's school. I've been to several hundred, and I've yet to find one better.

@Jason @WaffleHouse This is NOT how you order hash browns at Waffle House!

Let’s do this Atlanta @WaffleHouse

Your child will learn from apps built by students.📚💻

@Austen I haven’t seen a valuable loyalty program for in-US travel. Only international programs are worth it.

I travel a ton but is there a loyalty program that is worth it enough to actually optimize for? I just book whatever is cheap and easy whenever I see it.
