In the world of technology, some changes seem to happen with the snap of a finger.
A new operating system update hits your phone, and bam! You've got a next-gen gesture navigation system and all sorts of other interface changes.
The cause and effect are both immediate and obvious.Other times, change can happen in a much more subdued and piecemeal manner — an evolution-like progression, with subtle and often insignificant-seeming shifts showing up bit by bit over time.
In and of themselves, each shift may not look like much.
But add them all together, and you realize a massive transformation has been building up in front of your eyes (you know, the whole "seeing the forest for the trees" thing).
