AI: We’re only at stage 4 out of 10!

--

Generative AIs like GPT-4 are already capable of delivering impressive performances on certain tasks, though they remain uneven. However, it’s easy to envision these technologies evolving further. So, what might the capabilities of AI be in 10, 20, or even 50 years? By extending the exercise to technology serving major societal challenges, it’s conceivable to outline up to 10 stages of AI, suggesting we’re currently only at stage 4. Curious to know what’s next?

What is Artificial Intelligence?

First, let’s return to the basics! In 2023, it doesn’t take long to find excellent reports offering a detailed history and definition of artificial intelligence. I recommend three below, and I don’t intend to linger on this part, as there’s plenty of well-made documentation:

I won’t insult you by suggesting reading the Wikipedia page on AI, but I assure you it’s detailed and very informative! For this article, here’s the definition we’ve adopted at Tomorrow Theory: AI is a technology aiming to simulate and reproduce human capacities to learn, think, and interact. Once this is established, it’s clear there’s a difference between the very first attempts at AI over 50 years ago, GPT-4 today, and the AIs seen in science fiction works. In fact, it’s amusing to distinguish 10 stages of artificial intelligence evolution. And whether it reassures you or not, GPT-4 is only at stage 4 out of 10!

For each stage, I offer a quick definition below, the main characteristics, some concrete examples of capabilities at this stage, and the impacts and challenges for society in general. If the early stages correspond to consensus widely found among AI experts, the more prospective stages are still subject to discussion, and what I propose below simply reflects my vision and understanding of AI’s potential for the future.

1/10 — Early symbolic AI (1950–1970)

The early symbolic AI period represents the dawn of artificial intelligence, where researchers explored the possibility of creating machines that could mimic certain aspects of human intelligence.

Characteristics

  • Formal logic: These systems used formal logic, a mathematical approach to represent and manipulate concepts. Formal logic allowed these systems to execute reasoning based on sets of logical rules.
  • Rule-based systems: AI was programmed with sets of explicit rules. These rules dictated how the system should react to certain inputs or situations.
  • Imitation of thought processes: The goal was to simulate certain aspects of human intelligence, such as problem-solving and language understanding, using computer models.
  • Lack of learning: Unlike modern AI systems, these early forms of AI couldn’t learn new information or adapt to novel situations. Their operation depended entirely on preprogrammed rules.

Example

ELIZA ELIZA was developed in the 1960s by Joseph Weizenbaum at MIT. It was one of the first programs to attempt to simulate a human conversation. ELIZA used a script, often called “DOCTOR,” which mimicked a Rogerian psychotherapist. It relied on text transformation rules to respond to user inputs. For instance, if a user said, “I feel sad,” ELIZA could respond, “Why do you say you feel sad?”

Impacts

Although ELIZA could create an illusion of understanding and conversation, its responses were entirely based on text manipulation rules without any real understanding of language or context. Nonetheless, ELIZA sparked debates on the nature of intelligence and the possibility of artificially reproducing it. Weizenbaum himself was critical of the excessive use and overinterpretation of his program’s capabilities.
