As sensing and computing have become ultra-low power and ubiquitous, we have entered an era of physical/digital convergence. This physical/digital convergence is bringing about new opportunities (usages) as well as challenges (end-to-end architectures). The talk will show examples ranging from static sensing and simple data analytics to the emerging (r)evolution towards artificial intelligence. Using these examples, I will attempt to outline areas of research in workload analysis as well as novel end-to-end architectures.
