Machine learning is a family of techniques that is used in the development of artificial intelligence. A more explicit algorithm that results in the same behavior would still be AI, but it wouldn’t be machine learning.

Secondly, even if the problem of aligning a general AI with human interests can be solved at all, it will *not* be like Isaac Asimov’s Three Laws of Robotics. As your own source states, Asimov’s laws are woefully insufficient, as is the general approach of specifying an explicit set of rules.
