This is a perfect case of disruptive technology fitting Clayton C. theory: first small low-power optical fiber lasers evolve for low-key industrial jobs, then many small systems integrated and scaled up in one large system that changes the battleground.
Still the entire disruption theory is more an intellectual exercise then useful tool – it’s always used backward to describe some historical development that happened but fails entirely as predicting tool.
Clayton used an example of mini mills in steel industry as a disruption case. I happened to be in in steel industry in that time and was involved in mini mill planning. There is nothing disruptive in mini mills it’s just more energy efficient technology/business process solution in a very conservative industry that barely changed in 100 years.
