As agents take on more decisions, the cost of being wrong goes up. So does the value of context.
Let's take a look at a travel site like Expedia. Even today, with years of transaction history, it struggles to recommend well from 2,000 options. Now imagine delegating that decision entirely to an Expedia agent. The failure mode gets worse. The trust requirement skyrockets.
At that point, travel history alone is insufficient. The agent needs to understand demographic info, taste, rhythm of life, novelty tolerance, comfort thresholds. The decision space spills across domains.
The amount of information required only increases as decision-making is delegated.
