This seems like the key. HN is definitely biased towards simpler, smaller tools. (And that's not a bad thing!). The most compelling JVM stories I hear are all from much larger scale enterprise settings.

Kafka being a good example. It's very good at what it does, but painful to manage and usually not worth the pain for anyone who's not in a mega enterprise.

Because in real life, real world applications software is large, long running and needs to be bulletproof. Clis are not powering the world's infrastructure via piped bash scripts. It really baffles me what people actually do as software engineers on here with some of the nonsense that gets thrown around.

IntelliJ IDEA is reasonably fast, but of course its hard to make a big desktop app in java be fast.
