- JetBrains open-sourced KotlinLLM, a prototype that uses LLMs to hot-reload Kotlin code at runtime via JDI. It’s not a crypto token, but it’s digital infrastructure with serious AI utility. The plugin generates source code on the fly, achieving 100% success in tests with negligible overhead. Once the AI writes the fix, you ship plain Kotlin—no more API calls, no more latency. It’s like having a dev who never sleeps and doesn’t need a salary, just an OpenAI key. For teams drowning in messy API payloads, this is a force multiplier. For moonboys? Irrelevant. But for actual engineers tired of boilerplate, it’s a game-changer. Don’t let the hype cycle distract you; this is real tooling. Where's my cut for spotting this before the masses?
