Microsoft has just revealed its plans to launch GPT-4 next week. This will power a new version of ChatGPT that could let you create AI videos and music.
In episode 13 of the Quantum Consciousness series, Justin Riddle discusses how microtubules are the most likely candidate to be a universal quantum computer that acts as a single executive unit in cells. First off, computer scientists are trying to model human behavior using neural networks that treat individual neurons as the base unit. But unicellular organisms are able to do many of the things that we consider to be human behavior! How does a single-cell lifeform perform this complex behavior? As Stuart Hameroff puts it, “neuron doctrine is an insult to neurons,” referring to the complexity of a single cell. Let’s look inside a cell, what makes it tick? Many think the DNA holds some secret code or algorithm that is executing the decision-making process of the cell. However, the microscope reveals a different story where the microtubules are performing a vast array of complex behaviors: swimming towards food, away from predators, coordinating protein delivery and creation within the cell. This begs the question: how do microtubules work? Well, they are single proteins organized into helical cylinders. What is going on here? Typically, we think of a protein’s function as being determined by its structure but the function of a single protein repeated into tubes is tough to unravel. Stuart Hameroff proposed that perhaps these tubulin proteins are acting as bits of information and the whole tube is working as a universal computer that can be programmed to fit any situation. Given the limitations of digital computation, Roger Penrose was looking for a quantum computer in biology and Stuart Hameroff was looking for more than a digital computation explanation. Hence, the Hameroff-Penrose model of microtubules as quantum computers was born. If microtubules are quantum computers, then each cell would possess a central executive hub for rapidly integrating information from across the cell and to turn that information into a single action plan that could be quickly disseminated. Furthermore, the computation would get a “quantum” speed-up in that exponentially large search spaces could be tackled in a reasonable timeframe. If microtubules are indeed quantum computers, then modern science has greatly underestimated the processing power of a single cell, let alone the entire human brain.

Brave new world let’s create happiness for everyone by putting microelectrode arrays in our brains but be careful not to create a situation like death by ecstacy by Larry Niven.
In the brain, pleasure is generated by a handful of brain regions called, “hedonic hotspots.” If you were to stimulate these regions directly, you would likely feel pleasurable sensations. However, not all of the hedonic hotspots are the same–some generate the raw sensations of pleasure whereas others are responsible for consciously interpreting and elaborating on the raw pleasure produced by the other hotspots. In this video, in addition to exploring the neuroscience of pleasure, we’ll see how understanding pleasure, happiness, meaning, and purpose can help us live better lives.
The event that shaped the world of Blade Runner is an event you’ve probably never heard of: World War Terminus. CJ explores the origin of Do Androids Dream of Electric Sheep’s environmental desolation and asks: did it happen in the movie, too?
Why do some people love Impressionist paintings like Claude Monet’s “Water Lilies” (1906) while others can’t understand the hype? The question of aesthetic taste has stumped scholars for centuries. Now, neuroscientists at the California Institute of Technology (CalTech) say they have come closer to decoding how the brain decides which artworks it deems good or attractive.
In a study published in the scientific journal Nature Communications, CalTech Professor John O’Doherty and other researchers propose that the mind creates an opinion of an artwork after dissecting it into discrete elements. Basic features, such as color and texture, and complex qualities, like style, are ranked and weighed individually to make a judgment.
This video was creating using multiple AI tools. Script was generated using ChatGPT, the noration voice was generated with Elevenlabs.io, background audio was generated with AudioLDM model and finally images were created with Stable Diffusion using Illuminati Diffusion v1.1 model. The script itself was a source for prompts at image generation stage.
There were still some human input. Particularly I generated several images for each part of the script and choose the most appealing ones. I did also manually combine noration with background music. But mostly it was done in a way that each part of the process might be completely automated.
My music score for Rotwang’s robot in the silent German expressionist film METROPOLIS by Fritz Lang. 1927.
This film had a major influence on me, but that would come later. When I saw it for the first time I was 9 years old. Little did I know, this scene in particular would haunt me to this day.
