Tom: I heard that in Finland, a robot called Elias can speak 23 languages. This robot teaches many subjects like languages and maths to school students.

Lan: Wow! Can it interact with students?

Tom: Yes. Students can practise English with Elias in real time. Elias can even do a Gangnam style dance for the students.

Lan: Sounds exciting. I think children would enjoy studying in a class with Elias.

Tom: Exactly! This robot is patient and doesn't feel tired repeating words. It can also ask questions that are suitable for the students’ level.

Lan: So students can answer questions which are not too difficult, and they won't feel embarrassed when they make mistakes, right?

Tom: Definitely I think one day robot teachers will replace human teachers.

Lan: I don't think so. They can't teach students how to behave

Tom: Hmm...That's true. Also robots don't have emotional connections with students like humans do

Lan: One more thing is that robots can't solve problems between students...
