"need"? Of course not. Though I do see it being capable of much more sophisticated autocomplete. Like a tab-complete that is aware of what you've already typed in the command and gives you only compatible remaining flags, or could tab-complete information available in the environment, like recognize it's running in Kubernetes and let you tab through running hosts or commands that'd make sense from 'here', etc, etc.

Sure, it's all things a very nice and complicated algorithm could do, but ... that's all "AI" thus far. There have been zero actual artificial intelligences created.
