Should founders let Meta, Google, and TikTok's AI automation run their campaigns?

Mostly yes for execution, never for inputs: Advantage+, Performance Max, and Smart+ now outperform manual setups for most small advertisers, but they are only as good as the creative, conversion signals, and guardrails you feed them. Meta's Andromeda engine specifically rewards many genuinely different creative concepts, so your job shifts from audience hacking to supplying diverse ads and clean conversion data. Keep control of negative keywords, exclusions, and budget caps until the system has 30-plus conversions a month to learn from.
