One thing I have a question: what about business that doesn't have hospitaly/B2C? Many exemples relies on the F&B business, which is quite special in the fact that one of the core value proposition is directly hospitality, so we could argue that "adding more hospitality" is actually their core business already.

But what about a company which is more in B2B, and where procurement will be more rationalized (e.g RFP, which is often regulated)?

One thing as well: this is moat from an organization point of view, but unfortunately not for the individual: soft skills are often easier to get than hard skills, and there is so already a competition on the job market for the client-facing roles, even before AI arrival: like Sales / Business Developers / Account Managers (or more internal roles to try to build something that the client would need, like Product Managers)
