#35Tea. Earl Grey. Hot.
It occurred to me last week that phrase is prompt engineering. He is giving the essential info to specify what he wants presumably because a shorter specification would yield a different result. I wonder if star trek replicators are deterministic. Does Picards frequent ordering of Tea Early Grey Hot make the probability of someone ordering "tea" more likely to be TEGH, and thus if Picard ordered TEGH frequently enoug…

>It occurred to me last week that phrase is prompt engineering. He is giving the essential info to specify what he wants presumably because a shorter specification would yield a different result. I think it's less that and more to illustrate Picard's personality traits and command style for the viewer - precise, methodical, practical, no nonsense. The computers in Star Trek are perfectly capable of understanding casu…

#37This kinda reminds me of Terence McKenna talking about his experience with DMT. He met "self-replicating machine elves". One of them told him, "don't be stuck in shock/wonder", and "do what we're doing". Then he noticed that these 'beings' were creating various 'physical' objects in front of him with sound. Like they were "singing" these objects into existence. He called it, "glossolalia", or "speaking in tongues". T…
In particular the 20-100 hz range.
There's a simple explanation for all of this. The sound wave frequencies are about coincident with the brain wave frequencies used in representing conscious thought. Signals of audio and visual perception in the brain are meant to be similar, you want to recognize the same object as the cause of both light and sound signals. So perhaps information in the optical nerve is serialized in a manner that makes the wave form similar to sound waves coming from the same direction and same characteristic length scale. Of course on psychedelics you can use sound or perhaps even blinking lights to create erroneous perceptions.

After that part, I'm afraid I don't see the connection to the manufacturing technique that is the subject of this discussion.

And of course, in the Silmarillion, Eru Iluvatar "sings" the universe into form and creates deities that form harmonies (and then, dissonance).
