Which is more efficient:1) a car that costs $100 million in terms of other possible goods and is assured of never killing anyone
2) a car that costs $100 in terms of other possible goods and kills on average 100 motorists per year
There is no right or wrong answer. Some will value the first as a more efficient use of their resources while others the second. Technology can never tell us "the best" use of our available resources as "the best" is always a value judgement encumbent upon human beings for its existence. Science and technology can only let us know of our available options; there are no 'essential' measuremetns of value.
The person you quoted seems to competely and fundamentally misunderstand the issues discussed and advanced by the Chicago School. Implicit in the whole post was that the particular person speaking knows 'what's best' for the human race as a whole.
