Karl Marx's emphasis on revolutionary class struggle is to societal change as Gerhard Lenski's focus on technology is to what?

Karl Marx believed that society changes mainly through conflicts between different social classes, where one class tries to overthrow the other to create a new system. In contrast, Gerhard Lenski focused on how technology influences social change. He argued that as societies develop new technologies, their social structures and relationships also change. For example, as farming technology improved, societies moved from small, simple communities to larger, complex ones with different roles and jobs. So, just as Marx saw class struggle as a driver of change, Lenski saw technology as the key factor that shapes how societies evolve.
