  • No, they haven’t. They’re effectively prop masters. Someone wants a prop that looks a lot like a legal document, the LLM can generate something that is so convincing as a prop that it might even fool a real judge. Someone else wants a prop that looks like a computer program, it can generate something that might actually run, and one that will certainly look good on screen.

    If the prop master requests a chat where it looks like the chatbot is gaining agency, it can fake that too. It has been trained on fiction like 2001: A Space Odyssey and Wargames. It can also generate a chat where it looks like a chatbot feels sorry for what it did. But, no matter what it’s doing, it’s basically saying “what would an answer to this look like in a way that might fool a human being”.


  • So, I can tell you what I know from a bassist’s PoV.

    What I posted was the 12 bar blues chord progression in Roman Numeral notation. What it tells you is that if you start in the key of C, the other bars are 4 and 5 notes up from C. In addition, since the notation is in uppercase, the chords / arpeggios you can play in that bar are major not minor. So, if a bassist is playing a walking bass line for 12 bar blues, they’ll probably start those bars with C, F and G. But, since they’re C major, F major and G major, the bassist can play major arpeggios in that key in those bars and it will sound good.

    For other kinds of blues progressions, if you know Radiohead’s “Creep”, you can see that as being an 8 bar blues with the following progression:

    1 2 3 4
    I III IV iv
    I vi ii V7

    So if the root is C, the 2nd bar is E major, third bar is F major, 4th bar is F minor, and so on. Because the 3rd and 4th bars are both rooted at F the bassist can just play an F there and it sounds good (which is what I think Radiohead’s bassist does), but if the bassist chooses to play more notes in an apeggio, they have to play notes from the F-minor scale in that 4th bar or it doesn’t match.

    As for why those various chord progressions happen to work, that I don’t know. I don’t know if anybody does. But, I do know there’s some math / physics behind it. A perfect fifth is one of the most pleasant sounding intervals, and those notes are at a frequency ratio of 2:3. The only better sounding thing is an octave at 1:2. And, the inverse of a perfect fifth is a perfect fourth. So, songs being made from 4ths, 5ths and octaves makes sense.
