Operator Fusion Meets the 'Kill Chain': Compiler Ethics Behind DeepMind Researcher's Resignation

Google DeepMind researcher Alex Turner resigned because the company joined a US Department of Defense military cooperation project. This isn't the first time. After the Project Maven controversy in 2018, Google withdrew from that drone image recognition project under employee pressure. But this time, the scope of cooperation is deeper—expanding from simple CV annotation to co-building underlying infrastructure like AI compilers, inference optimization, and edge deployment. The question is: Does an optimization engineer who saves 10% memory bandwidth through operator fusion really need to be held responsible for the accuracy of final strike targets?
