Originally, science defined artificial intelligence as the ability of a machine to imitate human abilities such as logical thinking, learning, planning and creativity. Today we distinguish between "strong AI", where an intelligent computer system is indistinguishable from the human mind, and "weak AI", where algorithms can take over very specific tasks after training. All AI applications known so far are weak AI.
The difference that ChatGPT in particular makes now is active participation. We can easily try out this AI tool ourselves and actively experience its amazing capabilities.
