AI History and Milestones

The term 'artificial intelligence' was first coined at a conference at Dartmouth College in 1956.
Deep Blue became the first computer to defeat a world chess champion when it beat Garry Kasparov in 1997.
The first AI chatbot, ELIZA, was created in 1966 and could simulate a psychotherapist conversation.
AlphaGo defeated world Go champion Lee Sedol in 2016, a decade earlier than experts predicted was possible.
ChatGPT reached 100 million users in just two months after launch, making it the fastest-growing consumer application in history.
The Turing Test, proposed in 1950, remains a foundational concept for evaluating machine intelligence.
The first neural network, the Perceptron, was invented in 1958 at Cornell University.
GPT-3, released in 2020, was trained on 570 gigabytes of text data and had 175 billion parameters.

Large language models don't actually understand language; they predict the most likely next word based on patterns in training data.
Training GPT-4 is estimated to have cost over 100 million dollars in computing resources alone.
Claude, created by Anthropic, was trained using a technique called Constitutional AI to make it more helpful and harmless.
The largest AI models now contain trillions of parameters, each one a number adjusted during training.
Transformers, the architecture behind modern AI chatbots, were invented by Google researchers in 2017.
AI models can hallucinate, confidently stating false information that sounds entirely plausible.
The context window of advanced models can hold over 100,000 tokens, equivalent to a small novel.
Fine-tuning a large model on specific data can cost anywhere from a few hundred to millions of dollars.

AI image generators can create photorealistic images in seconds, but often struggle with hands and text.
Current AI cannot truly reason; it excels at pattern matching but lacks genuine understanding.
AI models trained on internet text can inadvertently learn and reproduce societal biases.
Generative AI can write code, but studies show it introduces bugs about 25% of the time without human review.
AI cannot form new memories during a conversation; each interaction starts fresh without prior context.
Machine learning models can identify cancer in medical scans with accuracy matching or exceeding human doctors.
AI systems are vulnerable to adversarial attacks, where small changes to input can cause wildly incorrect outputs.
Current AI lacks common sense reasoning that even young children possess naturally.

Over 4 billion devices now have voice assistants powered by AI, from smartphones to smart speakers.
Netflix estimates that its AI recommendation system saves the company one billion dollars annually by reducing subscriber churn.
AI-powered spam filters block over 100 million spam emails every minute worldwide.
Self-driving cars use AI to process data from dozens of sensors simultaneously to navigate roads.
AI algorithms determine what appears in social media feeds for billions of users every day.
Predictive text on smartphones uses machine learning trained on billions of text messages.
Banks use AI to detect fraud, analysing thousands of transactions per second for suspicious patterns.
AI-powered language translation now covers over 100 languages and processes billions of words daily.

The World Economic Forum estimates AI will create 97 million new jobs by 2025 while displacing 85 million existing ones.
Radiologists, paralegals, and customer service agents are among the jobs most likely to be augmented by AI.
AI prompt engineering has emerged as a new profession with salaries exceeding $300,000 in some markets.
Goldman Sachs estimates that AI could automate 300 million full-time jobs globally in the coming decade.
Tasks requiring creativity, emotional intelligence, and complex problem-solving remain difficult for AI to perform.
The global AI market is projected to exceed 1.5 trillion dollars by 2030.

Training a single large AI model can emit as much carbon as five cars over their entire lifetimes.
Data centres powering AI consume about 1-2% of global electricity, a figure that continues to grow.
Microsoft and Google have both reported significant increases in carbon emissions due to AI infrastructure expansion.
AI is also being used to optimise energy grids, reducing overall power consumption by up to 40% in some applications.
The water used to cool AI data centres in some regions exceeds the water consumption of entire cities.
Researchers are developing more efficient AI architectures to reduce the environmental footprint of machine learning.

The human brain uses about 20 watts of power; training GPT-4 used the equivalent of millions of watts over months.
A human child learns language from roughly 50 million words by age ten; large language models train on trillions of words.
AI can process millions of documents in seconds, a task that would take humans years to complete.
Despite their power, AI models struggle with tasks humans find trivial, like understanding sarcasm or irony.
The human brain has approximately 86 billion neurons; large neural networks have billions of artificial parameters.
Humans can learn from a single example; AI typically requires thousands or millions of examples to learn a pattern.
