Any application that can be written in a system language, eventually will be

Summary

Ok, the title of this post may seem provocative, kinda clickbaity but here is the thing, 19 years ago (2007) Jeff Atwood wrote his famous blog post where he declared that "Any application that can be written in JavaScript, will eventually be written in JavaScript.", coined the now-famous Atwood's Law. It was a a blog post based on an even older one from Tim Berners-Lee on the Principles of Design and his axiom/rule of least power. It was a prophetic observation about accessibility. JavaScript wasn't the fastest or the most elegant language, but it was the most available. It ran everywhere the web ran. Accessibility won. We saw JavaScript everywhere, on the web, on the server with Node, on IoT devices, on Desktop with Electon, on Mobile with React Native, on Enterprise automation with Google Apps Script, even on Machine Learning applications with Tensorflow.js... even on places where the core is not written in JS like blockchain and NoSQL DBs, Javascript became the defacto choice as interface. For years, we defaulted to interpreted languages for greenfield projects because developer time was expensive, and compute was cheap. We optimized for "writing speed," not "running speed.". In 2026, that math has broken. Also for years we had numerous debates about which language is "the best" (a pointless debate IMO), in 2026 devs write 90% of the code using natural language, through an LLM. Today I believe we are seeing the emergence of a new corollary, driven by two entirely different forces, Economy & AI. So here I am to declare a new law: Everything that can be written in a system language, eventually will be written in a system language by an LLM. I am not here to declare the death of Java, Ruby, JS etc etc, there are numerous articles the last 2 decades declaring their death and these languages are still here. However the accessibility of languages like Rust/Go has increased drammatically. There are studies with benchmarks that saw for example that Python can be over 70x...
