Here's an easy non-AI example: In the past, a 'computer' was literally a person [1]. If you needed to synthesize large amounts of data, you needed to split the task among a team of people writing things down and then a team of people to check their work afte…
Look up Amdahl's Law and Universal Scalability Law. The math doesn't care whether the nodes are people, CPUs or language models. If agent A's next action depends on what agent B decided, you've introduced a sequential dependency.
Theoretically, each of those steps is parallelizable to some extent. Amdahl's law equivalent here would be that some delays are outside the reach of an organization to improve. For instance, a building permit will take the time it takes to be examined based on an external public administration.
