First of all, I'm going to talk about some jobs that have been replaced by machines. This is the case of many big shopping malls, where shop assistants have been replaced by cash tills. It has happened in Alcampo in Motril. The worst thing of this advance is that many employees have been laid off their jobs, increasing the number of unemployed.
As far as I'm concerned, there aren't machines that have replaced teachers. For me, a teacher can't be replaced by any machine because a teacher can set you challenges to overcome, if you don't understand something, he can explain it to you by many different ways until you understand it, he can support you with some ideas.... All these things can't be done by machines. From my point of view, technology is like a tool which many teachers use to teach. Nonetheless, technology doesn't teach us.
