"The sensors in our current systems include off-the-shelf webcams, because our current systems are research prototypes. But an ideal sensor might, for example, sense physical material with high fidelity while being blind to human beings. Such sensors are more likely to be developed if we demonstrate the need for them.
"We are not proposing a future with cameras everywhere."
@akkartik "Physical sensors are the future" is not the take I thought I'd see on there. But, it's fine, computing trends is kind of a circle. Someone in 100 years is just bound to re-invent something with loads of physical buttons and call it a "key board".
