Technology has changed over the years by using many different materials (ex. wood, stone, metal), power of them (ex. from a water wheels to grind grain to machines to gind grain much more). Sometimes the technology has even gotten worse! I can't give you an example of that because I don't know many of them. I hope this helped you.
