Ex-quant explains why AI crushes benchmarks but not your business: the missing ingredient is feedback loops

A 30-minute talk by ex-quant paulabartabajo, recorded from his keynote at Infintech Montenegro, tackles why AI dominates benchmarks yet delivers little business impact. His thesis: AI labs hill-climb benchmarks by scoring outputs and feeding the signal back, and most companies deploying AI lack exactly this feedback ingredient. He argues you can apply the same loop to your own agents — score outputs, close the loop with Skills, and scale from one human to many agents. Agenda covers quant-to-AI-engineer transition, benchmark vs. real business impact, what an AI agent really is, tool calling, feedback loops, and the judgment-vs-execution split.
