This is absolutely mind-blowing! The sheer amount of determination to get something like this done is out-of-this-world! I’ve only ever seen anime characters demonstrate this sort of resolve. A devil fruit was definitely awakened during this process.

It was a real pleasure and a lot of fun to be the first guest of the new Cause & Effect Podcast. Thank you, @schickling.dev , for being such a great host, and thank you @effect-ts.bsky.social for pushing the boundaries of building production-grade software with TypeScript!
