Audience worries that validating each field via events (label, description, etc.) would require many new forms and UI screens, inflating complexity. Garofolo: you're not forced to go this way, but a task-driven UI keeps each form small (you rarely submit a giant multi-field form), so more screens but each less complex. He finds the overall model less complex than MVC-CRUD — 'more things of less complexity' — comparing events to coins rolling into their slots in a piggy bank, versus MVC-CRUD's tangled validation code.
