You need to know what you are doing, before you can use AI to assist. Asking AI to write you a script to do something, will cause you to spend a lot of time on troubleshooting and getting it right.

Asking an ServiceNow trained AI to optimize a script you already had, will work, as long as you check the changes. 

And always remember: any AI tool is trained on multiple sources, so not specific to your instance. It could take more time to feed the information that AI needs to get an answer, than to just do it yourself.
