ABSTRACT The budding yeast Saccharomyces cerevisiae has moved beyond an evolved and domesticated single‐celled microorganism into a deliberately engineered biological substrate. Advances in synthetic genomics, illustrated by the international Synthetic Yeast Genome (Sc2.0) project, have reframed the yeast genome as a designable and programmable system. This article examines how locus standardisation, genome refactoring, controlled genomic plasticity and orthogonal regulatory systems collectively establish yeast as a programmable platform. Yeast is then viewed as an analogue of electronic systems in which genetic circuits, memory and population‐level computation are compared to logic gates, storage and distributed system architectures. These capabilities position yeast to move beyond conventional metabolic engineering towards hybrid systems that integrate biological information processing with electronic and computational components. Achieving such integration requires careful consideration of the interfaces between biological and electronic domains, including how biological states can be coupled to electronic systems through electrochemical, chemical, optical and mechanical transduction, and how electronic inputs can be delivered in forms that can be recognised and processed by engineered cells. Finally, both the principal bottlenecks and key enabling advances are discussed, highlighting how recent developments suggest that synthetic yeast is approaching readiness as a foundational platform for bioelectronic and hybrid living systems.
