It might not be a killer app for you, but it's a killer app for me as an engineer, and I'm definitely not alone. To give a concrete example, I used it to write and test a VSCode extension that provides autocomplete and type-checking for environment variables in 46 programming languages[1]. It was the first VSCode extension I've written and I have zero experience in the majority of those languages. The whole project took a little over a week. Without ChatGPT, it would have taken months to add support for so many languages. 1 - https://www.envkey.com/integrations/vscode https://www.envkey.com/integrations/vscode
