What Hacker News says

This is something that interests me a lot. In my own personal experience, ChatGPT is awesome at troubleshooting, it's given me terminal commands that are perfect and use the exact flags needed to identify and then fix the problem. Why is there this massive disparity in experience? Is it the automatic routing that ChatGPT auto is doing? Does it just so happen that I've hit all the "common" issues (one was flashing an ESP32 to play around with WiFi motion detection - https://github.com/francescopace/espectre) but even then, I just don't get this "ChatGPT is shit" output that even the author is seeing.
In Why does AI tell you to use Terminal so much?

Show HN: ESPectre – Motion detection based on Wi-Fi spectre analysis

Hi everyone, I'm the author of ESPectre. This is an open-source (GPLv3) project that uses Wi-Fi signal analysis to detect motion using CSI data, and it has already garnered almost 2,000 stars in two weeks. Key technical details: - The system does NOT use Machine Learning, it relies purely on Math. — Runs in real-time on a super affordable chip like the ESP32. - It integrates seamlessly with Home Assistant via MQTT.
