I find it interesting that those that should know, frequently assume that mankind is not capable of changing/learning through immersion. We all can adapt very quickly if there is only one option.
In the US, especially Texas where the state and public school systems are confronted with a HUGE influx of non English speaking aliens. The schools almost all choose bi-lingual education (with poor results), rather than full immersion in English. You think educators would be smarter. Actually, the teachers are smarter, but it's the state and local governments that are not.
I still believe that it is politics that is driving this boat not results, same with the metric system.
I was out yesterday in Beaufort 3.5 with my formula board and 11.0 and hit a top speed of 23 knots.
