I've not found it to be so, but you are welcome to your own evaluation, friend. :)
In general, x1 tends to be analogous to an English subject and x2 like an English object for gismu where that applies. At any rate, I don't think of memorizing even 1300 completely random place structures as any great mental burden compared to, for example, conjugating verbs in English, Spanish or French; or declining nouns in Latin.

Yes, if you only use the x1 and x2 of a gismu that's true. You are also not finished by memorizing 1300 place structures because Lujvo also have places and you can't be sure which places of the words on which the Lujvo is build get actually used for that purpose.
This was going to be a reply in a discussion between ChristianKl and MattG in another thread about conlangs, but their discussion seemed to have enough significance, independent of the original topic, to deserve a thread of its own. If I'm doing this correctly (this sentence is an after-the-fact update), then you should be able to link to the original comments that inspired this thread here: http://lesswrong.com/r/discussion/lw/n0h/linguistic_mechanisms_for_less_wrong_cognition/cxb2
Is a lack of ambiguity necessary for clear thinking? Are there times when it's better to be ambiguous? This came up in the context of the extent to which a conlang should discourage ambiguity, as a means of encouraging cognitive correctness by its users. It seems to me that something is being taken for granted here, that ambiguity is necessarily an impediment to clear thinking. And I certainly agree that it can be. But if detail or specificity are the opposites of ambiguity, then surely maximal detail or specificity is undesirable when the extra information isn't relevant, so that a conlang would benefit from not requiring users to minimize ambiguity.
Moving away from the concept of conlangs, this opens up some interesting (at least to me) questions. Exactly what does "ambiguity" mean? Is there, for each speech act, an optimal level of ambiguity, and how much can be gained by achieving it? Are there reasons why a certain, minimal degree of ambiguity might be desirable beyond avoiding irrelevant information?
