The word “robot” can be defined in many different ways, and that affects whether this has already happened, or how soon it may happen in the future.
If robot means remote controlled machine, think Battle Bots, or if it means something with a robotic arm, then it’s probably already happened.
If robot means human shaped machine, then I’d guess if it hasn’t happened yet, if only because of the expense.
If robot means sensors, processing, and actuators, like I learned in school, then I’m guessing it hasn’t happened yet, simply because it’s more work than a machine that follows a routine, but I could easily be wrong.
If robot means fully functional human sized android type robot with integrated processing then who knows? If it also requires AI, then I’m guessing it’s a ways off.
I just went to check the previous thread, and I think there’s miscommunication both ways here.
They read your post as “I’m trying Linux, but it’s even hard to get monitors to work.” So, they responded, “I haven’t had a problem with monitors on Linux in decades.”
There’s not much else they can say, as you weren’t really asking for advice, so you didn’t give any technical details, but you were still complaining about something that they like.
Meanwhile, you read them as you said, “well MY displays work just fine!” So their replies seem utterly baffling, defensive, and unhelpful from your perspective.
