Sunil Sadasivan reflects on Sunil Pai's 'senior engineer death spiral' essay

Engineering leader Sunil Sadasivan writes about re-reading Sunil Pai's essay on senior engineers feeling stuck as their fields evolve. Sadasivan argues that first principles thinking—asking why something is being built and how it helps users—is what separates the best engineers he's managed, regardless of their background.
