Physicists are getting close to the point where we can test a regime where some people claim quantum theory doesn't apply. This is because objects that we can manipulate in the lab are going close to some kind of mesoscale. And there you have something like a quantum probe like an elementary particle interacting with this larger object which could be a large mass, a large molecule and so on. You really don't know whether the combined system will or not obey quantum theory. It will have the same quantitative structures quantum theory by will be a different theory.
I interview Oxford physicist Chiara Marletto, who has been working on constructor theory for several years. She's published papers on its applications to various fields, including those of information, thermodynamics, life, and probability. We discuss the origins and motivations of constructor theory, problems the theory may solve, current research programs, the universal constructor, response to potential criticisms, why constructor theory can explain more of Reality than the prevailing conception, and more.
