Artificial Intelligence Valuation ——The Impact on Automation, BioTech, ChatBots,
FinTech, B2B2C, and Other Industries
The origins of AI can be traced back to ancient myths and stories of mechanical beings with human-like capabilities. However, the modern development of AI is rooted in the mid-twentieth century: a. Early Concepts (Antiquity to Nineteenth Century): The concept of creating artificial beings with human-like intelligence dates back to ancient civilizations. For instance, in Greek mythology, there are stories of automatons like Talos and Pandora. In the Middle Ages, alchemists and inventors attempted to create mechanical beings. However, these were more in the realm of myth and folklore than actual technology.
b. Early Computational Devices (Nineteenth Century): The nineteenth century saw the invention of early computational devices like Charles Babbage’s Analytical Engine, which was a mechanical general-purpose computer. These devices laid the theoretical foundation for the idea of automating computation.
c. Alan Turing and his Test (1930s–1950s): Alan Turing, a gifted British mathematician and computer scientist, is often considered one of the founding figures of AI. In his 1936 paper, he introduced the concept of a “universal machine” (now known as a Turing
machine) that could simulate any other machine.. Early AI Research (1950s–1960s): The term “artificial intelligence” was coined in 1956 at the Dartmouth Workshop, which marked the beginning of AI as a formal field of study. Early AI
researchers like John McCarthy and Marvin Minsky developed the
first AI programs and explored symbolic logic and problem-solving techniques.
e. AI Winter (1970s–1980s): AI research faced significant challenges and funding cuts during the AI winter periods. Expectations had outpaced the capabilities of the technology at that time, leading to disappointment.
f. Resurgence and Machine Learning (1990s–Present): AI experienced a resurgence in the 1990s, driven in part by advancements in machine learning and neural networks. The development of
powerful computers and the availability of large datasets enabled
breakthroughs in areas like computer vision, natural language
processing, and reinforcement learning.
g. Contemporary AI (Twenty-First Century): The twenty-first
century has seen remarkable progress in AI, with applications in selfdriving cars, virtual assistants, recommendation systems, healthcare,
chatbots, generative artificial intelligence, and more. Deep learning,
a subfield of machine learning, has played a crucial role in these
advancements.
AI boasts a longstanding historical background. The progression
of AI has undergone a series of transformations, shifting from rulebased approaches to statistical methods and eventually to data-centric
techniques within domains such as computer vision, natural language
processing, and machine learning. The interdisciplinary character of AI
has resulted in its widespread implementation across various sectors,
including economics, manufacturing, healthcare, and defense technologies, thereby influencing contemporary business environments and
decision-making processes. The sustainable trajectory of AI development underscores the significance of human–machine collaboration and
a technological trajectory focused on computational capabilities, exerting
a substantial impact on society. The historical track record of AI has
influenced future expectations in several ways, as shown in Table 1.1:
The historical origins of AI have shaped the way people approach and
perceive the field. While there have been setbacks and disappointments,
1 INTRODUCTION 3
Table 1.1 History of artificial intelligence
Cycles of Hype and Disillusionment The history of AI has shown cycles of hype
followed by periods of disappointment, often
referred to as “AI winters”. These cycles
have made people cautious about
overestimating AI’s capabilities
Realistic Expectations Modern AI researchers and practitioners have
a more realistic understanding of AI’s
current capabilities and limitations. They
focus on solving specific, practical problems
rather than aiming for general human-level
intelligence
Ethical and Societal Concerns The historical development of AI has raised
concerns about job displacement, bias in
algorithms. These concerns shape the way AI
is developed and regulated today
Continuous Progress Despite past challenges, AI has made
significant progress, and this historical track
record of innovation fuels optimism about its
future potential. It encourages ongoing
research and investment in AI technologies
