"There are plenty of more important technological advancements from the past 200 years that are much more important than some of the ones listed. What about advances in waste and water treatment? Immunization vaccines? How about medical imaging equipment? Or the Electric Motor? Or Batteries? Or Refrigerators and Freezers? Or the rim fire or pin fire gun cartridge? Or Penicillin? Realistically there isn't any way to narrow down the list to the top 10 anyway; maybe we could do top 200 but that may be too limited also."
