"Design System" plays a critical role in bringing a common language and consistency in experience across different products and brands of the organisation, along with fuelling a collaborative approach towards design, making it easier for different team members to contribute. With observation of design systems, we can notice, almost all of them are having different structure and approach to define these, and almost none of them can be directly used in automation of design as they are not semantic in nature. Therefore most of these current approaches to design systems are not future-proof for tomorrow's design operations (DesOps). Samir coins the "Semantic Design System", that address this issue, and focuses building a design system, that is equally human-readable and at the same time understood by the machine for the next generation of design operation with automation, machine learning and artificial intelligence. The talk also introduces, what Samir believes as "Nuclear Design", an approach that helps in to lay out a framework that is the foundation for building design systems with semantics.
