Although AI is often misunderstood, its current explosion among the general public, reaching a million users in 5 days, can be explained by factors that can be transposed to the enterprise: firstly, the model's ability to be trained at lower cost; secondly, the availability of HR data has also increased tenfold, with the text corpora on which GAI bases its power being supplemented by data supplied by users. The advent of Generative AI is also due to the ease of interaction with the "machine". What will change and dictate the adoption of this tool is its ability to integrate into users' daily lives in an invisible, intuitive way, in the "flow of work".
