Actually, it's not that clear-cut. In the early 2020s, we were still uncertain about the capabilities that artificial intelligence systems could develop. A few ingredients were missing for them to be reliable and able to create results that would have value, commercial or otherwise.
However, by 2023, it was clear that these systems used multiple modes, not just text. Initially, there was a lot of talk about large language models, but today we are talking about multimodal artificial intelligence systems that are capable of using any mode that relies on digital information, including music, voice, video and images. These systems are enormous. In fact, their size is unknown, since there is no longer any scientific transparency in the publications of the industry's major players. We do not know what data is being used to train them. We also do not know which algorithms have been used.
We do know that these systems will continue to improve at a dizzying rate.
