Also known as optical computing or photonic computing, light-based computing is the usage of photons (or light) from lasers or diodes for computational purposes. For the most part, electronics and computers utilize electrons for computation.
Optical computing leverages an optical transistor, as opposed to the electronic transistors that Moore’s Law refers to. While data is channeled through photons, today’s technology still relies on processing information using logic and electrons.
To make light-based computing fully functional, there need to be microchips that use photons instead of electrons (i.e. a laser transistor).

Topological quantum computing is a brand new form of quantum computing being developed by Microsoft as they enter the race to build the world's first useful quantum computer. In this video I visited Microsoft’s quantum labs to see how they are making their topological quantum computers and learn how topology helps their quantum devices avoid noise by harnessing the power of Majorana quasiparticles which are made from an exotic form of superconductivity where the electrons behave like there is a Majorana particle there which has the special properties of topology.

Dangers of Science of Technology
This is a short animated film created by Steve Cutts back in 2016. Like so many other things, we have all grown numb to the reality of what mobile phones and social media have done to all of us. This animation is a cold slap in the face for us all to WAKE THE HELL UP! Put the GD phones down and reconnect with the real world around us.
A study suggests the dependence of children on their mobile phones could threaten the very fabric of society. Many teens are fanatics to be always available and are extremely uncomfortable if unable to communicate with their countless friends every day. If the trend continues, young people will soon be unable to form and maintain relationships without the help of a mobile, the study by a leading sociologist concludes.
A British child in four between the ages of five and 16 now has a mobile phone. In addition to making calls, young people use their phones to send millions of text messages to friends every day. The author of the study, Dr. Hisao Ishii said, teenagers can be seen taking advantage of every free minute to touch the base with their friends. It is not the content of communication but the act of keeping in touch what matters. And he warned: authentic conversation will be driven out by superficial communication, in which the act of bringing the which is leading to a deterioration in the quality of relationships, since the very fabric of society can be threatened.
Although Dr. Ishii's research was based on children in Japan, British psychologist have confirmed that the same trends apply to the UK child psychologist Dr. David Lewis said: "The mobile phone, like the Furby or Rubik's Cube in front of it, has developed into a gaming craze in Children like to feel as if they are not in the group, and think that without a phone they will be left out. It is like a tribal electronic drum. to keep up to date with a large group of knowledge, so that when they meet, they know the latest news and gossip.
Dr. Lewis approved the warning that in connection with personal computers and video games, mobile is having a detrimental effect on children's social skills. The mobile now often replaces the physical game, he explained. To develop the right friendships, you have to invest time with people, do things together. Speaking on the phone and sending lots of text messages will give the children a lot more knowledge but less friends. They replace quality to quantity. Sociologists have also warned that the popularity of e-mailing, text messaging and gaming on mobile phones affects other important activities such as reading leisure and studying. One-third of people aged between 16 and 20 prefer text messaging to all other forms of written communication, according to a survey last year by Mori for Vodafone. The handset manufacturers claim, however, that they are not on the market for those under 16 years of age. A government report last year highlighted the increased risk for children under 16 using mobile phones and a circular sent to schools suggests that under this age children should be allowed to make calls only in case of emergency.
Integrated Circuits, CPUs, GPUs, Systems on a Chip, Microcontroller Chips, and all the other different types of microchips are the brains of all the devices and technology that we use on a daily basis. But have you ever wondered how these microchips are made? Well, in this video, we're going to take a tour of a microchip fabrication plant or fab and walk you through the dozens of steps used to make a microchip. Specifically, we focus on how CPUs are made. CPU, GPU, and Smartphone Microchip manufacturing is a multi-trillion dollar industry, and each factory costs in the tens of billions of dollars. This is an overview of all the processes used to make a microchip, as well as an overview of a microchip factory. We're planning more videos on microchip manufacturing, such as a 3D animated factory tour.
This is the MOST complicated video we've made by FAR!! 4 different animators have been working on this video non-stop for the past 5 months, for a total of 1300 hours of research, modeling, script writing, animating, editing, animating again, rendering, and then more editing.

A Swiss startup claims to have created the world’s first “bioprocessor” by integrating human brain tissue into a digital processor.
FinalSpark claims that its Neuroplatform will “consume a million times less power than traditional digital processors” and is capable of learning and processing information.
Neuroplatform uses architecture that mixes hardware, software and biology, otherwise known as “wetware.” The platform contains four multi-electrode arrays (MEAs) which house living brain tissue, or organoids.
Each MEA holds four organoids, interfaced by eight electrodes used for both stimulation and recording, and uses analog convertors for data transfer. The platform contains a life-support system for the living tissue and also monitoring cameras. A special software system allows researchers to enter commands and also read outputs.
6G wireless communication could be coming soon, as one of the major problems associated with the technology appears to have been solved.
Up to now, one of the main obstacles to 6G communication has been the tiny size of the terahertz waves it uses. These are easily disrupted by obstacles like walls, furniture and living creatures.
