Detail: My experience is that commercially viable AI requires a leadership that gets AI and can execute very careful tech/product development facing end-to-end business problems, obsess over data quality, pivot and and manage risks in a way that's subtler than shutting the whole thing down. None of these are possible when attempting to transform a pre-existing business.
Consider AI and classic Google Search: in the best case scenario, AI will cannibalize on the search. In the worst case scenario, it will generate no lift. The middle ground is elusive at best.
What does seem to work across pre-existing businesses is when AI is used to provide embellishments/optional upsells. But of course that's not the dramatic transformation that a lot of people not in the scene seem to be expecting.
