[Podcast] Introduction to AI and differences between Strong AI and Weak AI

Written by Alana Team
on June 29, 2020

Inside Alana Podcast emerged as an initiative by Alana AI to disseminate knowledge about Artificial Intelligence and other related topics.

The purpose of this initial series is to bring information to all people interested in discussing the role of Artificial Intelligence in the future, how it will influence global organizations, and also the relationship between humans and technology.

The first season is anchored by presenter Regina Bittar, known for being Siri's first voice in Brazil, and we invited Alana AI's CTO, Marcellus Amadeus, to make an introduction about AI and explain the concepts of AI Strong and AI Weak.

Introduction to Artificial Intelligence

Talking about Artificial Intelligence is automatically thinking about science fiction, with super-intelligent robots or machines that speak and act like humans, but the reality is different. We are far from having an Ultron.

According to computer science, research in the field of AI is a search for "intelligent agents", that is, any device that can interact in its environment and take actions to maximize the chances of reaching a goal.

Marcellus explained that, although modern artificial intelligence began to be studied in the mid-1950s, by Alan Turing, the concept is something that appears at various times throughout history.

For example, Socrates, in the middle of 390 BC, began to consider the possibility of an algorithm that described human behavior and identified it as good or bad. This is the first historical record of something that resembles what we know as Artificial Intelligence today.


Alan Turing

He was a mathematician and computer scientist, who became popularly known for the film "The Imitation Game".

Alan was a visionary, while the computer field was beginning to take shape, he was already wondering about the ability of machines to think, and created a test to validate his theory.

Nowadays it is questionable whether this test would be the best method to define whether or not a machine is capable of thinking, but Turing's genius was beyond his time and inspired other people to advance in their studies.

In addition to him, other scholars also did tests to understand artificial intelligence, such as John Searle and the Chinese room test, and John McCarthy,  who enshrined the term "artificial intelligence" in 1956.

Strong AI vs. Weak AI

The definition of artificial intelligence is only one, but depending on the degree of understanding of the technology, it can be considered as Strong or Weak.

We can compare the two as: "where we are" (weak AI) versus "where we want to get to" (strong AI).


Weak AI

To call it Weak AI does not mean that it is bad, quite the contrary, current technologies are classified as such and are of high quality. See the evolution of chatbots, virtual assistants, and technologies for social networks, for example.

Being a Weak AI just means that it does not have full awareness to act in this independent way, as artificial intelligence is considered ideal in theory (Strong AI).

Strong AI

Strong AI is the concept of an ideal technology, which acts alone, like those that appear in films about artificial intelligence.

According to Marcellus, even the most optimistic of specialists in the field believes that it can take centuries to create a machine that has its conscience, but it may be that this level is never reached.

The development of an AI is always in search of perfection, but we are still far from something 100% similar to the human brain. On the other hand, this search for Strong AI is what makes current technologies so qualified and will certainly continue to evolve and innovate.
