2 Firstly they're very expensive.We must spend too much money to buy and fix them
3 Secondly,robots in factories are able to do everything the workers do , so robots make them jobless
4 Thirdly,robots in our homes will do all the housework for us , so we'll become lazy and inactive
5 In short , robots will do everything for us but they may not improve the quality of our lives
