According to a study published several years ago, mainstream languages seem to operate on an information density/speed tradeoff [1].The authors found that languages that are spoken faster seem to encode less information per syllable than those uttered at a slower pace.

This does seem to suggest that biology may be the limiting role in controlling the rate at which humans convey information. Indeed, the language mentioned in the article seems almost laughably cryptic and dense. However, I feel that the limitation of the mentioned study results from the fact that it treats information on a relatively limiting per syllable basis. Quijada seems to suggest that an artificially constructed language has the ability to incorporate all the implicit meanings of a phrase that are left unsaid in normal conversation.

Ultimately, while Quijada's project seems quite unlikely to catch on among those who are not fringe pseudoscientists, it poses interesting philosophical questions about the nature of speech and communication and perhaps earns its title as a "conceptual-art project."
