Deep learning doesn’t stop at llms. Honestly, language isn’t a great use case for them. They are—by nature—statistics machines, so if you have a fuck load of data to crunch, they can work very quickly to find patterns. The patterns might not always be correct, but if they are easy to check, then it might be faster to use them and modify the result compared to doing it all yourself.
I don’t know what this person does, though, and it will depend on the specifics of the situation for how they are used.
This is a forum. If you don’t get the joke, you can ask and have it explained to you. Most memes are some form of in-joke regardless, so you often have to do a bit of learning the first time.
What was off about your first comment was recognizing it for what it was before proceeding to miss the joke entirely.
What was off about your replies was trying to compare it to the Scottish coat of arms; if you know the Scottish coa, you probably wouldn’t associate it with piss yellow and white. If you don’t know it, you wouldn’t mix them up anyway.
