AI has the potential to be extremely powerful but it is also very new. People and organisations are just at the beginning of the learning process.
Sure but the hype has been about the 10x productivity increases and how less employees are needed. Also all the AGI/singularity stuff being just around the corner, not simply AI potentially making employees a lot more productive.
Which will probably be true at some point when we have become good at using AI, and maybe when AI has improved further as well.
