42 Berlin

Last week, 150+ people gave up their Tuesday evening to think seriously about AI. Most left with more questions than answers.

We consider that a success.

We opened Mai ist für AI at 42 Berlin with one simple question: what does AI actually need to be worth trusting? Hands went up, then came back down. Almost everyone uses it. Almost no one trusts it with anything that really matters. Turns out that’s a pretty good place to start a conversation.

We do mAI for exactly that reason. Not to hype AI, not to bury it. Just to make space for the kind of conversation that’s harder to find than it should be.

See you at the next one! 😉

Our March Piscine has officially begun. 🚀

Yesterday, over 170 newcomers walked through the doors of 42 Berlin to begin the ultimate adventure. To break the ice, we asked two simple questions: How are you feeling? and What’s an interesting fact about the person next to you?

The emotional spectrum in the room was quite impressive. Alongside ecstatic, focused, and serene, we also heard scarented, eepy, boop-beep, and the clear winner: bumbblefuzzed.

From the neighbor facts we learned that in this one room there is:
🎬 a former movie director and a circus performer
🌊 a researcher exploring underwater caves
🎹 musicians, marathon runners, and a Rubik’s cube speed-solver
⛰️ someone who climbed Kilimanjaro on a school trip

To all our bumbblefuzzed, eager, and fascinating new swimmers: welcome to 42 Berlin. 🤗

Introduce yourselves, lean on each other when the terminal gets confusing, and remember that collaboration is everything.

Good luck over the next 26 days! You’ve got this. 💙🏊‍♀️


Coding the Legacy: The Black Women Who Built Tech

From NASA’s early orbits to the future of AI ethics, these five visionaries didn’t just join the tech industry they built it. 🚀

▪️Katherine Johnson: The math behind the moon landing.
▪️Dorothy Vaughan: The FORTRAN pioneer.
▪️Dr. Gladys West: The genius who gave us GPS.
▪️Annie Easley: The code behind the Centaur rocket.
▪️Dr. Timnit Gebru: The leading voice in AI Ethics.

For Black History Month, we celebrate the logic and resilience that paved our way.💡

Which of these pioneers did you just discover today? Let us know in the comments 👇

It’s official we’re now two weeks into the first Piscine of the year. Some are coding for the very first time.
Others are diving back in for their second round.

Current Pisciner energy:

🔹 /*for*/
🔹Hopeful
🔹Focus
🔹Motivated :) Having fun, making friends
🔹Confused

We wish you all the best 🩵

Today we kicked off the very first full Piscine of 2026, with 150+ new pisciners diving into 4 weeks of intensive peer-driven learning.

This cohort already feels like its own little universe. In just a few hours we discovered we’ve got DJs in the room, a competitive wine taster, a chess teacher, a former professional football player, and a mechanical keyboard builder, plus people joining us from everywhere from Honduras to Syria to Portugal to Venezuela, Spain, Libya, India, and yes, a few rare Berlin natives spotted in the wild.

To everyone starting today: welcome to 42 Berlin. Ask questions, lean on your peers, take breaks, and enjoy the ride.

You’ve got this. 🏊‍♀️✨

PeerLearning

We closed our Python Discovery Piscine on Friday with a cosy little showcase and the most wholesome vibes. 🐍✨

Our participants shared their stories, their projects, the moments they surprised themselves, and the peers who got them through the stuck parts. Thank you for showing up for each other and for bringing such beautiful energy to our campus. 💛
