This example is just the tip of the spear in medical diagnosis as more data gets aggregated. Using data to diagnose skin cancer seems to be genuinely useful. What AI is best at is uncovering clearly measurable but overlooked variables that are more significant than even someone with expertise and experience can recognize, or when any one person’s experience is likely to be too limited to develop an intuitive judgment. What algorithms can’t do is provide vision or ideas or build up the sense of common purpose within a company. Entrepreneurship and innovation involve vision and risk. Metrics can only quantify what already exists. If you rely on them to tell you what to do, unmediated by human judgment, you’ll create a risk-averse business – which is ultimately a dead business.
