Behind an agent is a human that might use the product. I think customers/consumers will demand that their personal/subscription agent can access the product.
As someone that works for a company that gets a 100% score on ax-check, all the effort I've put into making it accessible for agents has not 10xed the growth numbers like I was told it would.
The Ai growth looks more like the very-long-term 2% (technically productivity growth from innovation), avoid assuming the hypesters are even close to accurate in their predictions
The ROI is for we the users, not the companies, only issues is that the agent's attention is way easier to hijack, so you have to maintain a different kind of attention when using them and never blindly trust their outputs.
