I think this is in jest, but to answer seriously: No, I think that's actually backwards, trying to make a language more "packed" will harm information flow. Evidence suggests the real limit is how quickly human brains can take ideas/qualia, convert them into abstractions, and encode the abstractions into language. This is because (A) very different languages still exhibit similar limits and (B) those limits appear to…
> So trying to make the language more "compact" would likely just waste precious brain-cycles on the compression step If you learned this new more compact language as your native language or to native fluency, I don't imagine you would need to go through a compression step, since all of your thoughts would already have happened in the compacted form.
One option is that what you're describing just isn't possible, that humans are already butting up against some kind of limit which is not avoidable simply by being raised with a different language.
Another option is that one can be raised to think in "pre-compressed" structures, but nobody does because it's a bad tradeoff, dropping "general thinking" performance with a worse impact than any "faster speaking" benefits. (Such as being simply slower, or more error-prone, or more demanding on attentional resources, etc.)
