# A quote from Matt Webb Source: [https://simonwillison.net/2026/Aug/21/matt-webb/](https://simonwillison.net/2026/Aug/21/matt-webb/) 21st August 2026 > After I released version 1\.0, I figured I would have to do the rotations myself\. So I sat down with ChatGPT and I didn’t get it to write the code, but I got it to educate me\. With a patient, interactive tutor, I was able to finally do what I hadn’t by reading books and asking mathematician friends – I learnt how to use quaternions just enough to make the app work\. So learning doesn’t stop just because I outsource a bunch of thinking to AI\. It pushes me to learn more\. I like that as an outcome\. —[Matt Webb](https://interconnected.org/home/2026/08/21/galactic),Galactic Compass 2: now with new augmented reality mode
