By replacing the teachers with robots, it will exacerbate the condition. The principle of utilitarianism should be applied as to reduce the problem of unemployment. Presently, if the government were to purchase the robots, and to replace the teachers, the compensation money that should be paid to the teachers is too costly for the government.
For the foreseeable future, robots will not be able to interact with humans (especially children) as effectively as another human would. Robots will surely be a powerful tool in education just like pencils, books, computers, and the internet are, but total replacement would be absurd. While robots will hopefully eliminate much of the need for.
