This is what the core debate is; the critical period hypothesis would say that there would be a difference (although 12 is right on the cusp so it's a bit hard to say for that case).
The critical period is for learning first languages, not second languages.
The core of the critical period hypothesis is for a first language, but there are a lot of linguists who maintain that it affects second language learning as well. This is more controversial than the first language critical period, but still not in the realm of serious controversy within the field (the general idea, not the specifics).
Quote:However, I don't think that without actually studying (as opposed to not doing anything, no school, just waiting for the language to come to you naturally by listening to people) you can never become fluent, not even after age 12.
AFAIK the majority of linguistic researchers would agree with that. Now, there are major controversies in language pedagogy over whether and how much second language teaching should be made to mimic first language acquisition. But I don't think anyone seriously argues that an adult (with a few rare exceptions) would be able to immerse themselves in a language environment and acquire a second language as a child -- that is, be able to speak indistinguishably from a native speaker, with no active effort, studying, dictionaries, SRS, etc. If this is possible, it happens so rarely that mentioning it is of little use for second language learners.
You can find examples of immigrants to the US who learned some English through pure immersion with little to no studying, and you can find some who actually have a fairly good functional command of the language. But I don't think you can find more than a handful (if any at all) who speak completely unaccented English with native-level grammar.
Quote:Even our own native languages are learnt by studying after some point. It's why English-speaking people are still taught English at school. I remember in my Dutch lessons I also had to learn grammar rules and lists of words and their definitions (I'm a native Dutch speaker).
Right; language acquisition doesn't give a child automatic control over the full range of the vocabulary of their language, formal/archaic grammar structures, or features of the "standard" or "educated" dialect of their language that differ from what they picked up in their local dialect. This issue is obscured because of the widespread misconception that regional dialects are inherently inferior to the educated dialect, or grammatically deficient in some way. People confuse not being able to express something using the educated dialect with not being able to express it at all. There's also the usual confusion between speech and writing; it's common to talk about "language" as including both, when there is a huge difference between the two in terms of cognition and acquisition.
