AI did the work. I still had to be there.

Gym Turnstile

I went to my jiu‑jitsu gym not to train, but to reverse‑engineer the turnstile. I didn’t crack it by hand; I pointed AI at it and let the AI do the work. My brother is building a management system for the gym, and the turnstile is where the data lives, who entered to train that day, who works out there daily. That data is valuable for a business owner because you can’t remember everyone who walks in.

The turnstile was a black box. After installation, the only way to export data was through a simple IP‑only endpoint on their Wi‑Fi network, and the export showed only a code for each person, not a name. Matching those codes to actual members required manual, repetitive work that was almost impossible to do daily.

AI Bridge

I used AI to track every request the export process makes and organized a script that pulls the data from the turnstile and inserts it into my brother’s system. I was there to judge how it should work because my brother is just starting in this area. I knew the problem existed, I knew the turnstile held the data, and I could see it was reachable. So I decided what to build and guided the AI accordingly.

Changing Skill Sets

For years, writing code was essential. You still need to understand how to code to guide AI effectively, but now the “how” can be delegated to AI. The real value lies in perceiving the problem and designing a solution. Knowing what to build and why is more important than just knowing how to code. Technical skill remains important, but it’s no longer sufficient on its own.

Responsibility

Even though AI did the heavy lifting, I own the security check before the system goes live. Responsibility and judgment can’t be delegated to AI; that would be unprofessional. The lesson here is to identify the problem, decide whether you’ll write the code yourself or use AI, and then take responsibility for the outcome.

Helping My Brother

Behind the scenes, I showed my brother how Claude Code works this week and paid for his first month of a Claude Pro subscription. He’s two years younger than me, an adult, and I’m helping him turn problem‑solving into income. Seeing his system take shape and his excitement made my day. That’s why I record these videos, to show how I’m changing my life and maybe motivate you to try something similar.

Getting Started

Start with a local business you know, a gym, a shop, anything where you can see a real problem. Charge a modest fee just enough to cover your code subscription. You won’t get rich overnight, but the experience will be invaluable. If this video motivates you to start building, let me know in the comments. See you in the next video.
