I know it's a British one, I was wondering what region, since OP was talking about his London accent.

Like that, yes.

Are you asking what the term means? Masking is basically wearing an imaginary mask to hide whatever about you isn't deemed "normal" by society. Some typical examples are people with ADHD focussing very hard on noticing when it's their turn to speak, people with autism forcing themselves to make eye contact, people with depression putting on a happy face. Normal Person cosplay.

I remember being extremely well entertained by awesome dragons, and that's it. Which means you're probably correct.

What Bale's native accent?

I am 100% convinced they had a masterpiece and then test audiences didn't get it and they went and changed everything around and added the prologue and gave away the entire twist at the start by explicitly telling the viewer where and when we are. Also made the dinosaurs weird for .... reasons...?

If "profit" is missing most of it because I'm distracted by my surroundings/what I'm doing while listening/falling asleep, then yeah.

Yeah and that still has to start small scale. People in the EU are perfectly fine switching to English where needed but they still speak their own languages otherwise. There's no need for an EU-wide language so a universal language is unlikely to start here at least.

After humans have started colonising other places in space, that's where I could see them lose their traditional languages.

That hypothetical universal language will have to start small scale, in a community such as the EU, and spread from there. Or am I misunderstanding what you're saying?

So that we have them at our disposal in case of inability to deal anymore, yes?

I know, I do like supporting creators though.

The only thing I like about them is that there's no ads.

Depends on what you think of as "sleep" and what processes are involved. Does Data's brain have brain waves that change to make him go unconscious? Is Data even "conscious" and what is "conscious" (there's some debate about that on the show)?
