It is good for me. I use it to automate several tasks in my job. It isn't a full programming language though.
AutoIt is typically used to produce utility software for Windows and to automate routine tasks, such as systems management, monitoring, maintenance, or software installation. It is also used to simulate user interaction, whereby an application is "driven" (via automated form entry, keypresses, mouse clicks, and so on).https://en.wikipedia.org/wiki/AutoIt
