Proliferation is the spread of weapons, technologies, or things useful in producing weapons or technologies to actors who did not previously have those things. The term "proliferation" is especially associated with the spread of weapons of mass destruction - such as nuclear weapons - or of technologies or materials useful in producing them. The term diffusion is sometimes used for the spread of other technologies, such as advanced biotechnological capabilities or advanced AI systems.
