I wanted to describe how the algorithm works, and show what it looks like to ship a project of that magnitude, and share some of the fun problems complexities that come up. I'd like to see more creatives using code as a way to bolster their projects and reducing tedious work for themselves with automation or deployment scripts, and I think Rust is a really great language for doing this, so I thought it would be inspiring to share how and why I'm doing it.

I agree that it would be overall more valuable to have the whole thing open source online, but sometimes I want to share how I solved problems without open sourcing all my code directly, for various personal reasons. But from the many comments I'm getting across the internet on the article it seems like people are getting a lot of value and motivation out of it, which was the intent, so that makes me happy.
