What’s expected of an AI-powered SMM tool?

As someone working on an AI platform that helps small businesses with marketing, I’ve been wondering: What's your expectations for an AI social media manager tool?

To give you more details, here are some questions I’d love to hear opinions on:

What should an AI agent in SMM know to create effective posts?

What kinds of posts should it write?

How much of social media posting can or should be automated by AI?

What’s currently trending on platforms like LinkedIn and X? Can AI effectively replicate or predict such trends?

Should AI focus more on addressing the audience’s pain points, or is there more value in leveraging trends and viral formats?
