Nobody has commented on this topic, I keep commenting myself. :-)

I am wondering if the following features of two of the different
algorithms described could be combined to simulate the effect of
government on language shift:

> * language "fitness" defined as the sum of the capabilities (natural resources) of all
> sites that language occupies;
> * with a certain probability, a person discards the mother language
> and adopts the language of another person.

I imagined something like a state controlling the access to natural
(and artifitial) resources on an area, so stimulating people on that
area to shift their language to the state's official language.

I've noted that many people speak English even here in Paris, either
at the university with foreign students or in turistic zones.
Sometimes some of them start speaking English to me when they note I'm
a foreigner, even when I started the conversation in French. So I
wondered if this type of thing could slowly take the whole world to
shift language towards English. I came to the conclusion that what
avoids this shift in many countries is that English (or whatever
"cultured-people" language) is not the official language, so the local
language keeps being more useful. It's not the case of some Amerindian
students I have at the university that must know Portuguese to access
the classes' information.

BTW, English seems to be the new "non-Barbarian language" as Greek and
Latin were before. Every cultured person is expected to know English.

Até mais!
