Three Rallies

Watched my 3 daughters play tennis. Built Rallynox for them. Started Raised Nimble because AI changes everything. Building in public.

I'm a dad of 3 tennis-playing daughters growing up in the AI era.

That made me build two things:

🎾 Rallynox — a post-match debrief web app for competitive tennis players

📩 Raised Nimble — a weekly newsletter on raising kids, AI can't replace

I'm building both in public.

Here's what this account is about 🧵

@eveyino Some executives absolutely speak in polished nonsense, but pretending most of them do all the time is just a lazy substitute for nuance.

Some LC-36 updates. Now that we’ve had access to the pad and integration facility we can share a bit of good news. The propellant farm, oxygen, liquid hydrogen and LNG tanks are all in good shape. This is good luck because these are very long lead items. The water tower is also good. The big support tower is damaged, but it can be repaired in place rather than torn down and replaced. The booster “Never Tell Me The Odds” and the three GS-2s that were onsite in the integration facility also look good.

I’ve seen some speculation that we might move directly to the 9x4 configuration, but we won’t do that. Rate manufacturing of 7x2 is going well, and we’re going to continue that at pace as planned and store the stages for use. In addition, we had already been working for some time on eliminating our transporter-erector in favor of an alternative vertical conop, and we’ll now go directly to that; so we don’t need a new transporter-erector.

We will fly again before the end of this year. Gradatim Ferociter.

1 in 10 American teens use AI for all or most of their schoolwork. Not for one hard subject. For most of it. That's from a new Pew survey. The number I can't stop thinking about isn't the 54%. It's the 10%.

My youngest spent 20 minutes on a math problem she could have looked up in 30 seconds. When she got it, the look on her face wasn't relief. It was something else. No shortcut gives you that feeling.

This week, a US university was about to film preschoolers during class to train AI. The consent form did not name a single AI company.

Parents read it twice, noticed the gaps, and refused to sign. The study was killed within days.

Doing 3 things with my daughters this weekend.

1. Read one real form together (a school waiver, a sports app).
2. Ask any AI chatbot the same question twice, 10 min apart, and compare.
3. Pause one ad and ask what it didn't tell you.

Five min each. Wire the muscle in 💪🧠.

Adaptability over memorization. Critical thinking over following instructions. And honestly, resilience. Tennis taught my kids more about handling failure and coming back than any classroom. The skill isn’t knowing the answer. It’s knowing how to figure it out when no one gives it to you.

Children in a kindergarten in Italy napping to the sound of birds singing.

@sciencegirl My girls would have thrived in this kindergarten. Instead they got car naps between tennis tournaments.

@TennisChannel @rolandgarros @carlosalcaraz Brad Gilbert covered in clay is the most Roland Garros thing I've ever seen. We'll take it while we wait for Carlos to come back.

@amitisinvesting The same thing happens in tennis. Everyone wants to drop their coach the second they lose a match and find the one whose student just won a tournament. Patience and conviction are rare in both games.
