An entirely different form of perfectionism has arisen in response to rapid technological change. Some techno-optimists, especially transhumanists, avow a form of perfectionism in which the capacity to determine good and trade off fundamental values, is expressed not by humans but by software, genetic engineering of humans, artificial intelligence. Skeptics assert that rather than perfect goodness, it would be only the appearance of perfect goodness, reinforced by persuasion technology and probably brute force of violent technological escalation, which would cause people to accept such rulers or rules authored by them.
