What makes SPEED an addiction?

What makes speed an addiction? Lots of people nod when I say society has lost control in a way that looks, feels and sounds just like addiction. But what are they nodding at? Countless people want to slow down in every way, but they cannot, even when they vow they’re going to change. They want to set limits on their technology use, they vow to “cut back,” they promise to be more available and engaged with their families, but they do not change. This is addiction: you cannot go any faster, and you cannot slow down, even when you want to.
