Never mind the AI hype - have you actually validated your hook, offer, and angle against real data? Not some gut-feel bullshit from a ChatGPT brainstorm.
If those three things are backed by a proper attribution model (and I hope you're not just counting last-click as "proven"), then iterate away. You'll survive.
If you've never run paid media before, the problem isn't AI, it's that you don't know how a winning creative is structured. Market maturity, core emotional trigger, angle, and a qualification gate for the offer - get those right first, or you're just burning budget on cost-per-click vanity metrics.
