>>I wonder though what things look like with super high dimensions.
You need only look to healthcare in the USA. Many, many professionals (some of which you never interact with) handing off patient cases to each other in a very carefully choreographed dance designed to meet legal and regulatory requirements; quality, safety, and care standards; financial responsibilities; and each individual's own personal standards for the quality of care they believe they provide.
In healthcare, we often view risks using the Swiss Cheese Model [1]. Everyone makes mistakes sometimes, but the system of checks and balances catches most of them before they reach the patient. Prescriber ordered the wrong dose of medicine in the inpatient setting? Pharmacy intercepts and starts making calls or sending messages to verify. Pharmacy approves the order because "that's what they ordered?" Nursing lays hands and eyes to every medicine administered and can 'stop the line' if they deem appropriate. Not to mention the technical safeguards and guardrails (e.g., clinical decision support systems) that are also supporting everyone involved.
But still, failures happen, and they can be catastrophic.
