A.I. ‐ Humanity's Final Invention?

humans rule Earth without competition but we're about to create something that may change that our last invention the most powerful tool weapon or maybe even entity artificial super intelligence this sounds like science fiction so let's start at the beginning intelligence is the ability to learn reason acquire Knowledge and Skills and use them to solve problems intelligence is power and we're the species that exploited it the most so much so that Humanity broke the game of Nature and took control but the journey there wasn't straightforward for most animals intelligence costs too much energy to be worth

it still if we track intelligence in the tree of species over time we can see lots of diverse forms of intelligence emerge the earliest brains were in flatworms 500 million years ago just a tiny cluster of neurons to handle basic body functions it took hundreds of millions of years for species to diversify and become more complex life conquered New environments gained new senses and had to contend with Fierce competition over resources but in nature all that matters is survival and brains are expensive so for almost all animals a narrow intelligence fit for a narrow range

of tasks was enough in some environments animals like birds octopuses and mammals evolved more complex neural structures for them it paid off to have more energy consuming skills like Advanced navigation and communication until 7 billion years ago the hominins emerged we don't know why but their brains grew faster than their relatives something was different about their intelligence very slowly it turned from narrow to General from a screwdriver to a multi-tool able to think about diverse Problems 2 million years ago homo erector saw the world differently from anyone before as something be understood and transformed they

controlled fire invented tools and created the first culture we probably emerged from them around 250,000 years ago with an even larger and more complex brain it enabled us to work together in large groups and to communicate complex thoughts we used our intelligence to improve our lives to ask how things work and why things are the way they are with each Discovery we asked more questions and pushed forward Ward preserving what we learned outpacing what evolution could do with genes knowledge Builds on knowledge progress was slow at first and then sped up exponentially agriculture writing medicine

astronomy or philosophy exploded into the world 200 years ago science took off and made us even better at learning about the world and speeding up progress 35 years ago the internet age began today we live in a world made to suit our needs created by us us for us this is incredibly new we forget how hard it was to get here how enormous the steps on the intelligence ladder were and how long it took to climb them but once we did we became the most powerful animal in the world in a heartbeat but we may

be in the process of changing this we're building machines that could be better at the very thing that gave us the power to conquer the planet Humanity's final invention artificial intelligence artificial intelligence or AI is software that performs mental tasks with a computer code that uses silicon instead of neurons to solve problems in the beginning AI was very simple lines of code on paper mere proofs of concept to demonstrate how machines could perform mental tasks only in the 1960s did we start seeing the first examples of what we would recognize as AI a chatbot in

1964 approach program to sort through molecules in 1965 slow specialized systems requiring experts to use them their intelligence was extremely narrow built for a single task inside a controlled environment the equivalent of flat worms 500 million years ago doing the minimum amount of mental work progress in AI research paused several times when researchers lost hope in the technology but just like changing environments create new niches for Life the world around AI changed between 1950 and 2000 computers got a billion times faster while programming became easier and widespread in 1972 AI could navigate a room in

1989 it could read handwritten numbers but it remained a fancy tool no match for humans until in 1997 an AI shocked the World by beating the world champion in chess proving that we could build machines that could surpass us but we calmed ourselves because a chest spot is quite stupid not a flatworm but maybe a bee only able to perform a specialized narrow task but within this narrow task it's so good that no human will ever again beat AI a chess as computers continued to improve AI became a powerful tool for more and more tasks

in 2004 it drove a robot on Mars in 2011 it began recommending YouTube videos to you but this was only possible because humans broke down problems into easyto digest chunks that computers could solve quickly until we taught AIS to teach themselves rise of the self-learning Machines this is not a technical video so we're massively oversimplifying here in a nutshell the sheer power of supercomputers was combined with the almost endless data collected in the information age to make a new generation of ai ai experts began drastically improving forms of AI software called neur neural networks enormously

huge networks of artificial neurons that start out being bad at their tasks they then used machine learning which is an umbrella term for many different training techniques and environments that allows algorithms to write their own code and improve themselves the scary thing is that we don't exactly know how they do it and what happens inside them just that it works and that what comes out the other end is a new type of AI a capable black box of code the these new AIS could Master complex skills extremely quickly with much less human help they were

still narrow intelligences but a huge step up in 2014 Facebook AI could identify faces with 97% accuracy in 2016 an AI beat the best humans in the incredibly complex game of Go in 2018 a self-learning AI learned chess in 4 hours just by playing against itself and then defeated the best specialized chess bot since then machine learning has been applied to reading image processing solving tests and much more many of these AIS are already better than humans for whatever narrow task they were trained but they still remained a simple tool AI still didn't seem that

big of a deal for most people and then came the chatbot chat GPT the work that went into it is massive it trained on nearly everything written on the internet to learn how to handle language which it now does better than most people it can summarize translate and help with some math problems it's incredibly more broad than any other system just a few years ago not crushing any single Benchmark but order of them at once many large tech companies are spending billions to build powerful competitors AI is already transforming customer service banking Healthcare marketing copyrighting

creative spaces and more AI generated content has already taken hold of social media YouTube and news websites elections are expected to be inundated by Propaganda and misinformation no one is sure how much good or harm can come from adopting AI everywhere change is scary there will be winners and losers one of the biggest questions governments and corporations have now is how to manage the transition to an AI boosted economy all these potential gains or risks are just the result of today's AI chat gpt's intelligence is a major step up but it remains narrow one it

can write a great essay in seconds it doesn't understand what it's writing but what if the AIS stopped being narrow General AI what makes humans different from current AI is our general intelligence humans can technically absorb any piece of knowledge and start working on any problem we're great at many very different skills and tasks from playing chess to writing or solving science puzzles not equally of course some of us are experts in some fields and beginners in others but we can technically do all of them in the past AI was narrow and able to become

good at one skill but was rather bad in all the others simply by building faster computers and pouring more money into AI training will get us new more powerful generations of AI but what is the next step for AI is to become a general intelligence like us an AGI if the AI improvement process continues as it has been it's not unlikely that AGI could be better in most or even all skills that humans can do we don't know how to build AGI how it will work or what it will be able to do since narrow

AIS today are capable of mastering one mental task quickly HGI might be able to do the same with all mental tasks so even if it starts out stupid and HGI might be able to become as smart and capable as a human while this sounds like science sence fiction most AI researchers think this will happen sometime this Century maybe already in a few years humanity is not ready for what will happen next not socially not economically not morally earlier we defined intelligence as the ability to learn reason acquire Knowledge and Skills and use them to solve

problems all things humans excel at an AGI as intelligent as even an average human would already disrupt modern civilization because they're not Bound by the same limitations as we are today's AIS like chat gbt already think and solve the tasks they were made for at least 10 times faster than even very skilled humans maybe AGI will be slower but it may also be faster maybe much faster and since HGI are software you could copy them endlessly as long as you have enough storage and run them in parallel there are 8 million scientists in the world

now imagine an AI copied a million times and put to work imagine 1 million scientists working 24/7 thinking 10 times faster than humans without being distracted only focused on the task they've been given what if suddenly HGI could do all intelligence-based jobs in the world from interpreting law to coding to creating animated YouTube videos better faster and much cheaper than humans would whoever controls this AGI suddenly own the economy and thinking bigger human progress is our intelligence applied to problems so what could a million agis achieve solve fundamental questions of science like dark energy invent

new technology that gives us Limitless energy fix climate change cure aging and cancer but then again sadly humans apply their intelligence not just for the benefit of all what if the agis are tasked to guide drones or pull the triggers in war or to engineer a virus that only kills people with green eyes or to create the most profitable social media so addictive that people starve in front of their screens the creation of AGI could reasonably be as big of an event as taming fire or electricity and give whoever invents it equally as much power

but now let's go one step further what if the potential of AGI doesn't stop here intelligence explosion intelligence and knowledge build and accelerate each other but humans are limited by biology and evolution once we evolved the right Hardware our software outpaced evolution by orders of magnitudes and within a heartbeat we ruled this planet but our software basically hasn't changed much since then which is why we have obesity and destroy the climate for short-term gains since AGI is software on a computer once it's smart enough to do AI research the rate of AI progress should speed

up a lot and that results in better AI That's better at AI research without much human involvement it may even be possible that AI could learn how to directly improve itself in which case some experts fear this feedback loop could be incredibly fast maybe just months or years after the first self-improving hii is switched on maybe it would actually take decades we simply don't know this is all speculative but such an intelligence explosion might lead to a true superintelligent entity we don't know what such a being would look like what its motives or goals would

be what would go on in its inner world we could be as laughably stupid to superintelligence as squirrels are to us unable to even comprehend its way of thinking this hypothetical scenario keeps many people up at night humanity is the only example we have of an animal becoming smarter than all others and we have not been kind to what we perceive as less intelligent beings AGI might be the last invention of humanity it's possible that it could become the most intelligent and therefore most powerful being on earth a God in a box that could exercise

its power to bring unimaginable wealth and happiness to humans while securing our future or it could subvert civilization and bring about our end with Humanity unable to come up with a way to stop it we'll look at some of these potential Futures in more videos but for now let's wrap up the only thing we know for sure is that today right now many of the largest and richest companies in the world are racing to create ever more powerful AIS whatever our future is we are running towards it who knows how long we have until we
