But what exactly is AI?
Nowadays, artificial intelligence is more and more present. But first you have to understand what it is. To keep it short and simple, an AI is a computer program capable of processing large amounts of data, reasoning, or even discerning patterns undetectable by humans.
An AI can be purely reactive, this is stage 1, in which case it will have no memory, no experience, it will simply be able to perceive the world at a given moment.
In stage 2, the AI will have limited memory, so it will retain information, and will know how to experience the past. In short, a level 2 AI already does a lot of things.
