The irony is that as marketing automation becomes 'complete', its effectiveness drops to zero because everyone is using it. When everyone has an AI SDR, no one answers their email. The only thing AI can't automate is the proof of work: the real relationships and the reputation that makes a customer believe you’ll still be around in six months.

Anyway, to answer your question: Autonomous Multi-Channel Agents (e.g., Emma, AgentsVerse) are close to what you asked for. They don't just draft posts; they identify "just-funded" leads, scrape LinkedIn, and run autonomous ad optimizations.

Edited: Just to clarify, I mentioned Emma and AgentsVerse as examples of where marketing automation is heading, not tools I've personally vetted for the specific capabilities listed.
