Technology has advanced so much that it's possible to communicate with someone we wouldn't normally communicate with through translation programs. However, something is still missing. Communication without tone of voice, facial expressions, and behaviors would be inadequate. The existence of thousands of cultures in the world is a wonderful thing. Every day, some of these cultures are slowly dying out. It's impossible to prevent this. It seems to me that in 200 years, cultural and linguistic diversity will gradually diminish.
This is behavioural, isn't it?
I think even faster. I reckon it would be a surprise if we haven't killed ourselves off in 200 years! :D
