I'm not so sure it comes down to language, because I suspect that our current language is about as developed as our intellect currently allows for. ... Most people are quite limited in their ability to use language. Also, according to the numerous people I have asked that have English as a second language, English is a more developed language than their native language is. I think our intellect needs to develop as much as our language... but don't worry, I have that covered.
Could I offer you a different thought about simulations... No one seems to come up with a very good reason for the simulations to be made... aside from marketing or research. What if it is a school? I study long term human survival by genetic and strategic adaptation and one huge problem is that we are developing an entirely new world (ecology) that is replacing the tribal world we developed in and are most adapted to. So the learning curve in the "new" world, our future, is huge. This time, as it appears to us, is right smack in the middle of that change. That is amazingly unique and would be the perfect place for a tribalist to get a start on being able to deal with a more technical "future" ecology. There is also that it's a lot easier to get things right the second time. What would you do if you woke from a simulation, perhaps 20 years old, in an advanced society? It makes one ponder.
