I'm all for becoming a more unified world, but why must we use a constructed language to do it?
And if we are using constructed languages why not Elvish or Klingon?
Yes Esperanto is equivalent to Klingon in my way of thinking
awesome. (many people I know never heard of it until I brought it up. And the only pop-culture reference to it I know is Katamari which holds many Esperanto jokes)
The whole "unified world" thing was a shot at the fact that here in the US we still use feet, furlongs, miles, oz... oz again (I really don't understand why we have two different measurement units with the same name. I find it very confusing) They use seemly random intervals which requires you to go out of your way to remember the different measurements. So if you want to find how big your home's yard is, you measure by feet... 3 feet to a yard, 22 yards to a chain, 10 chains to a furlong, and 1 furlong squared is an acre. So you've got to go down a bizzar conversion equation of seemingly random numbers to figure out how many acres of land you own. And even then, how many square miles is that? I call Bull S**T!
Communication is much more understandable to not-change. Unlike measurements, there is a lot of culture inbedded in the way people talk, and language has no standard yet. I don't believe any culture loss would happen if we changed to the metric system.
The point of Esperanto is to have have a simple language that does not break its own rules. The reason you "must use a constructed language" is because languages that formed 'naturally' develop in a way that makes no sense and therefor are prone to communication errors. Heck, nobody speaks proper english, and the reason is becaues english is a stupid mutant of a language. English is so unnessisarily complex that we have invented the term "grammar nazi" to describe people who actually understand it and try to teach others. Other languages are no better. Why use something that is flawed in its very construction? But thats a discussion for another time.
sorry, I'm having trouble staying on-topic
