Broadly speaking the problem with technocrats isn't always their expertise within their domain, but the ripple effects of their policies outside of their domain. The technocrat's policies might meet all of their metrics and be arguably correct within their area of expertise. Economic policies might seem sound in terms stock market metrics, but could be disastrous for consumers. Health policies might make sense from the perspective of public health metrics, but could be terrible for the economy.
