  The emergent gauge theories are reconsidered in light of supersymmetry and an
appropriate emergence conjecture is formulated. Accordingly, it might be
expected that only global symmetries are fundamental symmetries of Nature,
whereas local symmetries and associated massless gauge fields could solely
emerge due to spontaneous breaking of underlying spacetime symmetries involved,
such as relativistic invariance and supersymmetry. We further argue that this
breaking, taken in the form of the nonlinear sigma-model type pattern for
vector fields or superfields, puts essential restrictions on geometrical
degrees of freedom of a physical field system that makes it to adjust itself in
such a way that its global internal symmetry G turns into the local symmetry
G_{loc}. Remarkably, this emergence process may naturally be triggered by
supersymmetry, as is illustrated in detail by an example of a general
supersymmetric QED model which is then extended to the Standard Model and GUTs.
The requirement of vacuum stability in such class of models makes both Lorentz
invariance and supersymmetry to become spontaneously broken in the visible
sector. As a consequence, massless photon and other gauge bosons appear as the
corresponding Goldstone and pseudo-Goldstone zero modes and special local
invariance is simultaneously generated. Due to this invariance all possible
Lorentz violations are turned out to be completely cancelled out among
themselves. However, broken supersymmetry effects related to an existence of a
light pseudo-goldstino (being essentially a photino) are still left in the
theory. It typically appears in the low-energy particle spectrum as the eV
scale stable LSP or the electroweak scale long-lived NLSP, being in both cases
accompanied by a very light gravitino, that could be considered as some
observational signature in favor of emergent supersymmetric theories.
