Cross-platform development promised us sleek futuristic vehicles gliding smoothly across Linux, macOS, and Windows. Instead, we got a post-apocalyptic convoy hauling PyInstaller, DLLs, .NET runtime, Chromium (because why NOT bundle an entire browser?), Unity runtime, inpackage, and Node.js like they're essential survival supplies in Mad Max. The expectation: Write once, run anywhere! The reality: Write once, spend three weeks figuring out why it works on your machine but explodes on literally every other platform. Bonus points for the 500MB "lightweight" app that's basically Electron wearing a trench coat pretending to be native. Nothing says "cross-platform efficiency" quite like shipping half the internet just to display a button. Beautiful.
