I consider a sentence as a formatted thought. That implies a thought exists before it is expressed in words. There's a ton of thoughts in my head which can't be transformed into any language I speak. I wish I could somehow acquire some proficiency in the other thousands of languages spoken by humans on this planet, just to proof their immense lack of features.

Also our natural languages restrict information bandwidth to a few bytes per second. Imagine doing sports like tennis, chess or soccer at this speed...
