How We Got To This Moment in AI

The rich and complex history of AI is not punctuated by single 'eureka' moments; rather, it’s interlaced with numerous technological advancements and cultural shifts spanning across nearly a century.

1930's: The Birth of AI

The conception of AI dates back to the mid-20th century when the theoretical groundwork was laid out by forward-thinking minds who envisioned machines that could simulate human intelligence — such as Alan Turing, the computer scientist who, in 1936, created the Enigma encryption machine that helped shorten World War II.

This initial wave, known for symbolic reasoning (i.e., the process of using symbols and rules to manipulate and derive new knowledge or conclusions), centered around creating AI that could manipulate symbols and perform logical operations, akin to a human reasoning.

1980’s: The Rise of Machine Learning

While the symbolic AI approach showed early promise, it proved to be limited when it came to complex real-world applications. The value delivered by AI systems had fallen short of expectations, at least in the public eye.

This was followed by a time of minimal AI advancements, which led the mid 1930’s to the 1980’s to become referred to as the 'AI winter.'

However, this disappointment eventually prompted a focus on machine learning in the 1980s — inspiring many key developments, such as:

• A growing popularity of expert systems & reinforcement learning
• The emergence of Inductive Logic Programming (ILP) (i.e., inducing general logic from examples, with the goal of generalizing from specific instances to general concepts)
• Renewed interest in neural networks (which had originally been introduced in the 1950s)

These trends birthed a crucial pivot in the trajectory of AI, as now AI systems could learn and evolve without being explicitly programmed for each task.

1990’s & Early 2000’s: The Data Revolution

The advent and popularization of ‘Big Data’ (i.e., data warehousing and database management) combined with the growth of the internet in the 1990’s and early 2000’s had two major impacts:

• Increased computing power, allowing for the development of larger & more advanced AI systems
• More available data, which provided a greater amount of material for the development & enhancement of AI systems

Thus, this massive increase in data availability and computational power fueled the rise of more sophisticated machine learning algorithms.

2015 to Now: A Truly Transformative Decade

The adoption of AI has been increasing rapidly. Between 2017 and 2022, the number of companies integrating AI into their operations more than doubled, and 2021 marked a historic peak in AI funding — with reports indicating global AI investments ranging from $72 and $111.4 billion.
