I think when something becomes a management-level item in an org, like AI, it is a hard thing to switch unless it becomes a management-level problem.
Most of the orgs are responsible for this and will do whatever it takes politically or not, to justify the decision unless management overturns it.
I already mentioned the timelines. Cost is a beautiful line item in your balance sheet that can get things done pretty quickly, especially when it’s as big as AI. It took less than 2 quarters for us to go from “hey use ai in everything or get fired” to “hey we’re putting in default limits that are intentionally very low, if you need more, you’re going to need approvals”.
The stickiness of AI as a whole, let alone a specific provider is not that high as people are making it out to be.
Once the cost reaches a threshold, everything is doable. We ditched Datadog in less than a month. Someone I know had their company ditch slack in a quarter and google cloud usage of 100+ million in two. Everything is doable.
