It means the generations will be effected, and people will just flat out get dumber. The society will change, and there will be less doctors, and lawyers. If you can't pay attention in school, you cannot learn.
If you use technology you get more answers that are specific and back up with evidence. If students didn't have technology in school they would not be able to use certain web city and helpful tools to complete assignments or tasks. Technology can give students knowledge they could not get from a ordinary teacher.
