Why do we say data pins are the scarcest resource?
HLAHat
Scarcity just refers to availability. That is, we can load a whole row, which is quite a bit of data, but there aren't many data pins available to service the loaded row. Another interpretation of availability is that it takes a good bit of preprocessing before a row is ready to be sent over the pins. Because it is a scarce resource, we need to utilize it as much as possible whenever it is available to us, or it becomes a significant bottleneck.
