@oblomov@HalvarFlake IMO numbers are a good choice if you have limited resources and many problems -- which moles do we whack first? An example where numbers are good is e.g. managing climate change, where one of the purposes of a carbon tax is to help a consumer decide between (for example) locally sourced lobster and air-freighted apples from New Zealand. But we don't have a manager for Elon Musk, who thinks the answer is Mars. /
