Muscle Memory – Can you still write code without AI?

Developer of 6 years here, been using AI (increasingly) over the last year for most of my work. A few weeks back I started to look for new jobs as the current startup I work for is falling into pieces. "Do I need to do leetcode again?" - I thought. So I picked a few challenges and tried to solve them without an assistant.This felt impossible. What?! Is this the brainrot everyone is talking about? I mean I still read code every day, I just don't write it anymore. I could read and review the solution easily, but writing it myself felt like speaking a language I only understand, but cannot speak.Being the data hoarder I am, I immediately wanted numbers, so I built Muscle Memory to help me feed them.It's like leetcode but better. Challenges are more realistic, and I'd like to think the UX is more straightforward. It covers 12 languages and your code runs in a network-denied sandbox in your browser. No account needed.I want it to be a place to keep your hands sharp: short tasks, clear prompts, and difficulty that comes from solving the problem rather than figuring out what the question means.About the data (that I'm curious about):
