The evolutionary stages of developer brain expansion! Starting with the humble Notepad (barely firing neurons), progressing to VS Code (some decent neural activity), then leveling up to Vim (significant brain illumination), and finally reaching enlightenment with a custom text editor you built yourself. It's the coding equivalent of going from crawling to building your own rocket ship. The true mark of a developer isn't the code they write, but how unnecessarily complex they've made their text editing experience!
