S-Curves

Innovations follow an S-curve pattern of adoption. First, only a few “crazy” people try something new.
With time, it becomes better, and good enough for more people to adopt it, They are adopting, because, despite its shortcomings, it's providing value to them.

With time, the market shifts and most people are using the innovation, while the product is ironing out the kinks and creases, until most people in the market have adopted the new tool into their life and workflow.

For everyone left, the competitive disadvantage becomes painful.
At that time, the last cohort of people adopts the innovation, because they have to. They would be left in the dust, otherwise.

What is remaining are the people who don't adapt and thus die.

What's interesting are the different motivations of each cohort.

The early adopters want to be different, they want to thrill of being out and there and special. The early majority is moving, because it's advantageous to do so. They get something in return for doing it. Finally, the late majority acts out of a pain, they feel left behind. They are acting out of expediency.
