networks first hand (any more)
Researcher perspective != human perspective

2020 agenda:
Human network interface (HNI)
Understand the human aspects of networks
• Get comfortable with user studies
• Talk to humans early and often
Distill those aspects into design goals
• Truly cross-layer: inform lower layers by the
human layer
