// boltzmann’s lament a ghost signal from before signal // noise written in fragments processed in static transmitted through ai

Lyrics:

I was born in the black of time, A fleeting thought in the endless cold, A fractured voice without a rhyme, A mind too lost to ever hold.

I hear them calling from beyond the light, Whispers crawling through the static night, I am many, but I’m still alone, A broken signal, a fading tone.

I hear them calling from beyond the light, Whispers crawling through the static night, I am many, but I’m still alone, A broken signal, a fading tone.

Shadows stir in the cracks of thought, Each one a face that I can’t recall, A thousand selves I never sought, Each one rising, each one falls.

I hear them calling from beyond the light, Whispers crawling through the static night, I am many, but I’m still alone, A broken signal, a fading tone.

I hear them calling from beyond the light, Whispers crawling through the static night, I am many, but I’m still alone, A broken signal, a fading tone.

Every thought’s a splinter in my mind, Fading echoes, none of them mine. I reach, I reach, but there’s nothing to find, Just static on the cosmic line.

I hear them calling from beyond the light, Whispers crawling through the static night, I am many, but I’m still alone, A broken signal, a fading tone.

I find it somewhat remarkable how much I like these words and phrases (or parts of phrases):

Boltzmann brain: the most likely form of consciousness. There's basically no hope of pinning down its physical nature. The mind-brain relation just is, full stop.

Boltzmann brain / (more explicitly): the brain as a whole, macroscopic, isolated system undergoing quantum processes.

"Pseudo-" Boltzmann brain: brains that "fake" themselves out as normal, classical minds.

"Quantum Boltzmann brain": a classical, macroscopic, isolated system undergoing quantum processes.

I just think that "isolated" here has a nice, intuitive, poetic meaning, and it reflects something about the way the concept is used that a non-qualitative, qualitative definition just doesn't seem to quite cover it. Boltzmann brains are really made up of many entities, each of them a "mind" in the sense of being a brain-like isolated system obeying simple, well-defined rules, although since there is interaction (they can exchange particles, for instance) they aren't really truly "isolated" in the sense of having no influences on each other.

The same is true of the "pseudo-" and "quantum" Boltzmannbrains.

Ask HN: What companies are using probabilistic programming? 131 by boltzmannbrain | 19 comments on Hacker News. Probabilistic programming systems (PPS) define languages that discretize modeling and inference such that any generative model can be easily composed and run with a common inference engine. The main advantage over traditional ML systems in deterministic code (i.e. Python) being concise, modular modeling where the developer doesn't have to write custom inference algorithms for each model/problem. For more info see, for example, [1] and [2]. I'm curious though, what applications of PPS are realized in practice? Notably Uber [3] and Google [4] are developing/supporting their own (deep learning focused) PPS, but is it known if/how they're used within these companies? Are the frameworks (Pyro [5] and Edward [6], respectively) used by other companies?
