Why do I have to learn Yet Another Language to use this? Why can't it just use JavaScript or python for scripting?
As for Python (on the Windows OS) it doesn't come preinstalled, is far larger, less specific to automation, more confusing, and less convenient. There has been numerous Python attempts and projects to copy or make something similar to AutoHotkey and AutoIt, but they never caught on as much. AutoHotkey and AutoIt had already gained a reputation and became more firmly entrenched as the tools to use for automation tasks on Windows.
