According to a column "Writer's Twitter" on Nikkei BP, about one third of age under 6 already experienced Internet access in Japan. Potential problem will be; they might not think by themselves but copy & paste after searching information on the net. Also, if they just experience virtually through TV, PC, Internet, games etc., their emotion control might be unstable due to lack of real experiences. The age under 12 should experience real interactions with human and natures much more than virtual onces.
On 23rd of September, Nikkei Newspaper reported that cyber attacks frighten many nations such as USA, Korea, France, Israel etc. It's so called 5th dimension war field.
I have been telling at various occasions that physical weapons would have less power in the future battles but growing professionals to do/protect cyber attacking would be more important for nations since the most of important systems are controlled by ICT technologies and cyber attack should be faster than physical weapons launched.
In Japan, Ministry of Defense has only just started planning to set up Cyber Defense Troops. We need to watch how Democratic Party plans.
