The History of AI
Understanding the history of AI provides a broader context for generative AI.
The roots of AI can be traced back to early philosophers and mathematicians who aimed to mechanize reasoning. However, the groundwork for modern AI was established in the 19th and 20th centuries, epitomized by George Boole’s Boolean algebra and Alan Turing’s concept of thinking machines.
In 1943, Warren McCullouch and Walter Pitts introduced the first artificial neuron, a mathematical representation of a biological neuron. This marked the beginning of neural networks, which are now fundamental to modern AI.
In 1950, Alan Turing released a paper titled “Computing Machinery and Intelligence”, suggesting a test for machine intelligence. This Turing test is still used today as a way to think about the evaluation of AI systems.
The term “artificial intelligence” was first introduced in 1956 during the Dartmouth Summer Research Project on Artificial Intelligence, marking the onset of AI research.
Numerous discoveries during this period spurred an AI boom in the 1960s, propelled by funding from the US Department of Defense for potential military applications. Leading figures like Herbert Simon and Marvin Minsky optimistically predicted that machines would achieve human-level intelligence within a generation. However, the intricacies of AI proved more challenging than anticipated, resulting in reduced funding and research, leading to what’s termed the “AI winter”.
The 1980s saw a revival in AI interest due to the commercial success of expert systems, which were rule-based systems emulating human reasoning. These systems found applications in diverse sectors, including healthcare and finance. Yet, this resurgence was temporary, with another “AI winter” setting in by 1987.
During the 90s and 2000s, machine learning (ML) became the predominant approach in AI. The amount of data that became available during this period was instrumental to the success of ML. Unlike traditional rule-based systems, ML algorithms discern patterns directly from data, leading to a range of applications such as, email spam filters, recommendation systems like Netflix, and financial forecasting. Machine learning shifted the focus of AI from rule-based systems to data-driven systems.
A significant shift occurred in 2012. Enhanced computational power (boosted by GPUs), data availability, and advancements in neural network algorithms gave rise to deep learning, a subset of ML. Deep learning quickly outpaced other ML techniques, leading to a surge in AI research, funding, and applications. By 2022, global investments in AI were approximately $91 billion, accompanied by a substantial increase in job opportunities and specialists.
Today, the applications of machine learning-based AI are ubiquitous, ranging from basic tasks like spam filtering to complex ones like autonomous vehicles and medical diagnostics. Generative AI has emerged as a subset of ML, and has garnered significant attention due to its ability to create content, such as images, videos, audio, and text.
What is Generative AI?
AI/ML engineers employ various tools and techniques to convert data into machine learning models, which then make predictions or categorizations. For instance, a model trained on an image dataset of cats and dogs can differentiate between the two based on learned patterns.
ML models cater to diverse applications: video security systems detect humans and potential break-ins, voice assistants like Siri and Alexa process speech to respond to user queries, autonomous vehicles identify objects and make decisions, and the healthcare sector utilizes ML to spot anomalies in medical images, among other uses.
Considering its pervasive use, let’s term this “traditional AI” or “traditional ML”. Such AI classifies or predicts content, taking an input to produce an output, such as identifying whether an image has a cat or dog, determining the best route to a destination, or estimating the likelihood of a tumor in an X-ray image.
Generative AI, a subset of ML, utilizes neural networks to create content. Trained on extensive datasets such as images, videos, audio, or text, these models generate new content based on identified patterns. Different generative AI models cater to varied content types: for instance, image generation models like OpenAI’s DALL-E rely on extensive image datasets, while text generation models like OpenAI’s ChatGPT are trained on vast text datasets.
Generative AI can craft a plethora of content. Image models can create diverse images, emulating specific artists or art movements. Similarly, text models can mimic specific authors or genres, producing text ranging from technical to creative, or even generate code in various programming languages.
Encountering generative AI models for the first time might seem magical. They appear to conjure the requested content out of thin air. Asking a text generation model to write a poem or a story, or an image generation model to create a painting or a photograph, can be a surreal experience. Consider the following examples:
The following images were generated using DALL-E, an image generation model. The model was prompted to “Generate an image of a bustling renaissance-era city populated by anthropomorphic animals.”
Notice the intricate details such as the ornate architecture and the different species of animals. In less than a minute, the model produced two unique images, each with a distinct style.
Text generation models are no less impressive. The following text was generated by ChatGPT, a text generation model. The model was prompted to “Create a single paragraph writing prompt about a house cat living in a post-apocalyptic world.”
In a post-apocalyptic world where cities lie in ruins and nature has started to reclaim its dominion, a lone house cat named Luna roams the desolate streets. Once pampered and loved in a warm home, Luna now relies on her heightened senses and feline agility to navigate the challenges of this new world. Amidst the silence, she discovers remnants of human civilization, encounters mutated creatures, and befriends unlikely allies, all while uncovering the mysteries of what led to the world’s end. As Luna’s journey unfolds, she becomes a symbol of hope and resilience, proving that even in the darkest times, life finds a way.
How do Generative AI models work?
It was once believed that only humans could create art, write stories, or compose music. These were thought to be uniquely human traits that would be difficult to replicate. Generative AI has proven otherwise. These models can create content that’s indistinguishable from human-crafted content. This begs the question: how do these models work?
Generative AI models are trained on vast datasets, learning patterns and relationships between data points. For instance, a text generation model learns the contextual relationships between words, while an image generation model learns the visual relationships between pixels. These models then utilize these learned patterns to generate new content.
Here’s a simplified analogy describing how a text generation model goes from training to generation.
Imagine an apprentice learning to cook by studying recipes. They’re asked to study a cookbook containing a diverse array of recipes, ranging from simple to complex. While studying the recipes, they learn the relationships between ingredients and cooking instructions. The more recipes they study, the more patterns they learn. They begin to build a mental model of the cooking process.
They notice that the mention of “chocolate” and “sugar” are often followed by a baking process. They notice that terms like “boil” are frequently succeeded by ingredients like “water” or “pasta”. Their mentor helps them to learn by asking them to predict what comes next in a recipe. The mentor validates or corrects their predictions. This iterative process of prediction and feedback, over countless recipes, refines their understanding and hones the accuracy of their predictions.
After all of this training, the mentor poses a challenge: “Craft a recipe for a chocolate cake.” The apprentice draws from all the recipes they’ve studied, and their finely-tuned understanding of the cooking process, to create an original recipe. The newly created recipe might draw inspiration from previous recipes, but it stands as a unique creation.
Generative AI models are trained in a similar manner. They’re given access to vast datasets, such as images, videos, audio, or text. They learn the patterns and relationships between data points, and utilize this knowledge to generate new content.
This is of course a simplified explanation of how generative AI models work. The actual process is more complex, involving intricate mathematical calculations and algorithms. However, the underlying principle remains the same: these models learn patterns from data, and utilize this knowledge to generate new content.
Misconceptions of Generative AI
The impressive capabilities of generative AI models are evident in the content they produce. This often leads to misconceptions about their design and capabilities. Let’s address some of these misconceptions.
Are Generative AI models becoming self-aware?
Absolutely not. These models neither think nor feel and lack understanding of their generated content or the surrounding world. They are as self-aware as your toaster, with no architectural provision for anything resembling self-awareness. Give the right prompt and parameters, they may generate content that appears self-aware, but this is merely a reflection of their training data.
Are Generative AI models unbiased?
Unambiguously, no. These models are trained on vast amounts of human-generated data. Much of the data is sourced from the internet, infamous for its incivility, misinformation, and toxicity. These models mirror the biases of their training data, reflecting both subtle and glaring biases. Placing blind trust in these models is similar to trusting random people on the internet. The information they provide might be accurate, but it’s prudent to be skeptical.
Are Generative AI models accurate?
It depends on the use case. These models can be used to provide accurate information, however, they can also completely fabricate information. Any technology that can generate fiction from thin air has the ability to produce misinformation that appears authentic. This is a lesson that some people have learned the hard way. Always verify information from trusted sources.
Will AI replace my job?
The honest answer is, maybe. It depends on your profession. Starting in the 16th century, lamp lighters would light street lamps at dusk and extinguish them at dawn. Electricity and the light bulb made this profession obsolete. Similarly, automobiles made horse-drawn carriages obsolete. Historically, innovations such as these rendered certain jobs obsolete, while creating new ones. AI will likely reduce manpower for certain tasks, allowing fewer people to accomplish more. However, it will also create new jobs, requiring new skill sets, such as the emerging field of prompt engineering. As history consistently reveals, change is the only constant and adaptability is the key.
This section merely skims the surface of prevalent misconceptions surrounding generative AI. Recognizing their current usage and inevitable evolution is crucial. Grasping their capabilities and constraints will guide informed utilization.
What are the ethical concerns with Generative AI?

They can also be used to create deepfakes, which are synthetic media that appear authentic, potentially leading to misinformation and propaganda. The ability for these models to generate code in a wide range of programming languages can be used to perform automated and AI-assisted hacking.
Bias and Discrimination
Generative AI models will perpetuate and amplify societal biases present in their training data, leading to unfair or discriminatory outputs. Unchecked, this will lead to a feedback loop, where biased outputs are used as training data for future models, further amplifying the bias. The use of generative AI to make decisions that impact people’s lives, such as public policy, hiring, or criminal justice, can lead to unfair or discriminatory outcomes.
Misinformation and Fake News
Generative AI models can be used to create fake news, propaganda, or other forms of misinformation, and on an unprecedented scale. This can be used to influence public opinion, sway elections, or even incite violence. These are particularly concerning when coupled with deepfakes, which can be used to create fake videos of public figures.
Privacy
Vendor-provided models may be trained on either or both public and private data. The use of private data, such as medical records, can result in models inadvertently revealing sensitive information. The use of public data, such as social media posts, can be used to infer private information about individuals, leading to privacy violations or even blackmail.
Intellectual Property
Generative AI is moving faster than the legal system, raising questions about the ownership and rights to content generated by AI. This is especially concerning for content creators, such as artists, musicians, and writers, whose livelihoods depend on their creations.
De-personalization
Generative AI models are and will continue to be used to replace certain human interactions. Chatbots are already replacing customer service representatives, and this trend will likely continue in other areas. This can lead to a de-personalization of human interactions, potentially leading to reduced empathy and compassion.
Safety and Reliability
The use of generative AI in critical applications, such as autonomous vehicles, medical diagnostics, or military applications, raises concerns about safety and reliability. Unpredictable outputs can lead to accidents, injuries, or even loss of life. The use of generative AI in critical applications requires careful consideration and extensive testing.
Transparency and Accountability
Generative AI models are often black boxes, making it difficult to understand how they work or why they make certain decisions. These models commonly produce different outputs for the same input, making it difficult to predict their behavior. Who is responsible when a generative AI model makes a mistake? How can we ensure that these models are used responsibly? These are questions that require careful consideration and research.
This section merely scratches the surface of ethical concerns surrounding generative AI. Recognizing these concerns is crucial to understanding the technology’s impact on our lives.
