Artifacts that I don't like is the teacher robot because it cannot teach you really wanted to. It is going to work when it is taught to memorize as a computer system. Did not understand learning from it like people.
What I do not like the teacher robot. It really can not teach that. It goes on to teach in the system, it has memorized. Do not learn to understand it from the same people.
The invention that I don't like the teacher was a robot. Because it can't teach. It is to teach the job since it can memorize the computer system. Do not learn understanding from it like a man.
