Things with exponential growth start small.
If it has exponential growth and a high ceiling, it will grow to eat everything else, no matter their growth rate.
But everything starts small, and exponential things are no exception.
In fact, at the beginning, exponential things often have less growth than linear things.
When you see that, you might think "it's too early."
When the soil has been overturned–tilled–by a disruptive technology, that's the time when the majestic oaks of the next generation will take root.
That's when they will start growing as seedlings, even if they don't yet look impressive.
