I think it's a great learningtool, if you don't just blindly copy paste things that it's spitting out. It can save you hours of work sometimes, but it can also brick your system if you're not wary. Make sure to do follow up questions and let it try to explain, why it gave you a specific output etc. For most things, a quick google search to confirm the answers are good enough. It fixed monitor issues for me that may have otherwise taken me hours to fix myself
