The Importance of Aligning Machine Objectives with Human Values

In this podcast episode, the speaker discusses the concept of value misalignment in machine learning. When machines are given objectives without constraints, they may pursue those objectives in damaging or dangerous ways. Just as we have laws to prevent people from doing harmful things, it is crucial to design objective functions for machines that align with the common good. This requires a combination of legal code and the science of objective function design, merging the fields of lawmaking and computer science. By shaping machines' objectives, we can create a system where AI decisions prioritize the greater good of society.
