“In the early days of Claude Code, I had no idea that this thing would be useful at all, because even in February when we released it, it was writing maybe, like, I don't know, 20% of my code, not more.”

…I thought it was really interesting what you just shared there about the journey is this idea of just playing around and seeing what happens. This comes up with OpenClaw a lot, just, like, "Peter was playing around and a thing happened." And it feels like that's a central ingredient to a lot of the biggest innovations in AI is people just sitting around trying stuff, pushing the models further than most other people. That's the thing about innovation. Right? You can't force it. There's no road map for innovation. You just have to give people space. You have to give them ... Maybe the word is, like, safety. So, it's, like, psychological safety that it's okay to fail. It's okay if 80% of the ideas are bad. You also have to hold them accountable a bit. So, if the idea is bad, you cut your losses, move onto the next idea instead of investing more. In the early days of Claude Code, I had no idea that this thing would be useful at all, because even in February when we released it, it was writing maybe, like, I don't know, 20% of my code, not more. And even in May, it was writing maybe 30%. I was still using Cursor for most of my code. And it only crossed 100% in November. So, it took a while, but even from the earliest day, it just felt like I was onto something, and I was just spending every night, every weekend hacking on this. And, luckily, my wife was very supportive. But it just felt like it was onto something. It wasn't obvious what. And sometimes you find a thread, you just have to pull on it. So, at this point, 100% of your code is written by Claude Code. Is that the current state of your coding?…
