tom said this in ipc_class-1:
all computing is physical.
from the syllabus:
All computing is physical. We work with computational systems by taking action with our bodies, on devices. The construction of computing devices, and their use, consumes raw materials and energy as well. Computing, even when we call it “virtual”, “cloud”, or other names, always has physical consequences. This course is about how to design physical devices that we interact with using our bodies.
i’m still chewing on this.
