high technology makes...

I'm going to write about an answer of John's question.
Today, there are many high technologies in our life, and even children can communicate with other people by internet whithout meeting them directly. It is a very useful for us actually, of couse I use internet devices every day. However, I don't think that It's a really good think. According to scientist, many children who can't write Kanji directly are increasing because of using keyboard(prediction conversion) too much. And another scientist say that young people are getting shy and not good at talking face to face because they have many times to talk with other people by cell-phone or e-mail.
I think that thses are big morden problem and we shouldn't leave them never. It is not that it is good that all becomes convenient by high technology.
