Yes, Daleks are not robots, they're squishy tentacle space nazis inside mobile battle casing pepperpots that they call War Machines. The Terminator T1 however looks vaguely like such a pepperpot if you squint and are Doctor Who brained.
You're not making sense and you don't seem to know how to communicate what you want to say and when someone asks you to make sense you lash out because you don't know what to do. Is this a bit? Is this a social experiment? I honestly hope this is some kind of performance art piece and you're playing the role of someone who has lost their ability to communicate because they've been using AI too much to do their communicating. If so, 5 out of 7 perfect score chef's kiss no notes.
Same. I was on reddit for 10 years, wasn't banned once (and it's not like I never posted anything or didn't antagonise people). The enshittification is what made me leave.
Well you don't HAVE to start using "du". There are people who have been friends for years who still use "Sie". It's a mutual thing, when you feel comfortable with the other person you can tell them it's okay for them to call you "du" and usually they'll reciprocate (if they don't, they'll tell you and you go back to "Sie"). Or you can take a bit of a risk and just start using "du", without asking and the other person will follow (unless you gravely misjudged).
No I can't tell you how to know when it's the right time for that, don't ask me about how to behave like a human, I have social anxiety, hah. But normal people can intuitively tell when that moment has come.
Also there are constellations where you use "du" from the beginning and where it would be weird to use "Sie". Everyone on the internet is "du" unless you know you'd call them "Sie" in real life. Children are "du" and it's up to the adult to decide whether this 16 year old deserves a respectful "Sie". Young people tend to default to "du" among each other because "Sie" is stuffy and square.
Mind you, having grown up with this hasn't helped with learning Japanese because while there are certain similarities (desu/masu corresponds VERY vaguely with "Sie"), there are too many differences for my experience with my native language to be of much help. But if you'd drop the suffix from their name in Japanese, it's very safe to say you'd be on "du" in German.
I don't think I've ever seen a comprehensive explanation when to use "Sie" over "du" in German. Very, VERY basically it's this: if you're close to the other person, it's "du", otherwise "Sie". And then there's a gazillion constellations where it's not that easy and it seems learners keep finding more cases where what they learnt isn't applicable. Most of these are intuitive to native German speakers, some are difficult to decide even for us.
Not that I think German is special in this. The correct way to address someone is less about language rules that you can memorise, more something you learn to intuit by getting to know the intricacies of the culture and its social mores.
Regarding your language teacher: what are those two languages? They may have different rules on how a teacher/student relationship works.
What do you mean, "using AI"? Did you vibe-code? Does the AI help with journalling? If the latter: who wants that?
