  Systems of "living" polymers are ubiquitous in industry and are traditionally
realised using surfactants. Here I review the state-of-the-art of living
polymers and discuss non-equilibrium extensions that may be realised with
advanced synthetic chemistry or DNA functionalised by proteins. These systems
are not only interesting in order to realise novel "living" soft matter but can
also shed insight into how genomes are (topologically) regulated in vivo.
