There has been recent renewed interest in four-dimensional gauge theories with disconnected gauge groups. Such theories admit a rich spectrum extended topological operators generating global symmetries that go beyond the paradigm of groups and have a natural description in terms of higher fusion categories. I will present some of these ideas and comment on potential applications to geometric Langlands for disconnected groups and enumerative problems.
