Hello, thank you for taking the time to post your question!
Technological change drives economic growth mainly by increasing productivity. When a new technology allows firms and individuals to produce more goods and services with the same amount of resources (like labor or materials), it makes the entire economy more efficient.
This also directly impacts opportunity cost. Technology can help society use scarce resources more effectively or even create new ones. By automating tasks, it also lowers the opportunity cost of production, freeing up workers and capital to create even more value elsewhere.
Hopefully that gets you moving in the right direction! Feel free to reach out for a lesson if you have any questions beyond that! :)
