You've probably invested thousand of hours in learning all of those languages. Some just by circumstance/luck (maybe something like this? mom speaking 1 language, dad speaking another, both speaking a common language, the place you were in having another secondary language), some through your own efforts.

As always, the real question we can't really test is: what could you have done with probably literal person-years of study/research/leisure time, instead?

The investment you’re talking about is likely minimal. They only acquired two as an adult. There is time being spent there but learning a language is a fun and rewarding activity, which tends to become easier the more of them you know.

I speak 5 and had gotten used to being the exception; then I moved to Brussels and it’s normal here to meet people who speak even more, far more fluently than I do.

I was at this board game Meetup and met this young Ukrainian kid the other day. 13 years old. She was speaking fluent Russian and would switch to perfect French to speak to us, while following the conversation we were having in English. Her mom mentioned she speaks Ukrainian, and that her lessons are in Dutch at school. 13 years old - damn.

Anyway yeah when you have a good technique and some experience, learning a new language can be much quicker, and very passive.

There are different levels of investment and different level of expectations, and I say this as someone that speaks 3 languages (Romanian, English, French) and understands a few others at a basic level (German, Italian, Spanish).

Children have a very limited vocabulary and tend to make a lot of mistakes (grammar, word usage and pronunciation mistakes) and those mistakes are easily overlooked, especially by adults, since we tend to try to encourage them. Not the case for adult learners.

The second difficulty level is <<cultured>> native speaker. This is massively more difficult since you need to advance from maybe a basic 5-10-15k words to probably 20-40-60k words.

The investment level for C2 (proficiency according to https://en.wikipedia.org/wiki/Common_European_Framework_of_R...) is in the thousands of hours per language, including a ton of deliberate study.

To give you an example of C2, for Romanian you need to be at least a well educated high school student and really understand finer details of Romanian grammar. A native Romanian speaker who hasn't finished at least high school at a good high school is probably a bad C2, despite being a native speaker (or more likely a decent C1).

Now, you obviously don't need to be at the highest level for every language you know, but the gap in effort between levels is huge and people underestimate that. Most people that speak multiple languages are probably somewhere around B1-B2 at most of them. Even purely bilingual kids that learned both languages from birth have idiosyncrasies monolingual native speakers notice, for example.

The CEFR is a tool to evaluate proficiency, but it's misleading if you look at it as a "ladder" with "native" at the top". Most adults aren't C2 in their own native language, despite "investing" sometimes hundreds of thousands of hours "learning" it.

This video [https://www.youtube.com/watch?v=uqj5qPF_puU] by Olly Richards sums up my feelings on the definition of fluency. Personally, I believe even as early as B2 you can call yourself a fluent speaker, because it's roughly the level where you stop struggling to express your thoughts or to understand other people's. But it also depends how you have learned. B2 can look very different depending on whether it was leared in mostly academic vs literary vs spoken contexts.

Those tend to be cultural. My native language is French, but I cannot browse /r/france without wondering wtf everyone's talking about. I'm extremely disconnected from French culture as I moved out when I was 14, so I never experienced adulthood in French and I had to learn things like what "Pôle emploi" is or some such. I'm still C2 in French,

I also do make mistakes in English, but I catch plenty of native English speakers make egregious mistakes or not know fairly basic things about their own language. Another commenter mentioned the their/they're your/you're distinction is one that natives tend to mess up more often than non-natives; anecdotally, that seems correct to me.

> Those tend to be cultural.

Language is culture. A large part of language learning is learning culture, expressions, idioms.

If I say"white as cheese" to a Frenchman he won't understand what I mean because the average cheese in France is not white, unlike in Romania.

There's a post nearby where people are said to spend their time watching braindead youtube videos. My niece does that too.

You do know that within that spectrum there are thousands of useful and fun activities, right?

It's not "learn a million languages or be a meth head".

[olddustytrail]

Why don't you share some of the amazing skills you've acquired through not learning languages?

[oblio]

I speak 3 different languages, 2 at C2 level and 1 at ~B2 level. I understand 2 more at about B1 level.

Remember, always attack the idea, not the person.

[olddustytrail]

So you haven't actually learned any great skills through avoiding learning languages?

Why do you think that bolsters your idea?

[oblio]

Because Mister Offensive Tone, I know that there are trade offs to everything and sacrifices to be made with each choice. And I am not convinced that all that time I spent learning those other languages was spent wisely.

I have also noticed by moving to a country which is hyper focused on everyone learning many languages that it creates a ton of resentment and loss of other abilities, for example reduced STEM skills.

So the opportunity cost is real.
