probabilities (don't have to) multiply for agentic systems

One of the nuggets in Doctorow's Code is a liability (not an asset) is a reminder that sequential LLM's (e.g., in an agentic workflow) cause system success to decrease. If two sequential LLMs are each right 95% of the time, the cumulative correctness is 0.95*0.95=0.9025. That doesn't bode well for agentic systems, but then again what is human society if not a set of interdependent agents? No one…
