In my day job, we commonly create prototypes to sell the idea/concept to the higher ups, then if we get the green light, we throw the prototype in the bin and start from scratch to build it out properly.

I find this is where AI is genuinely useful, it lets us prototype an idea a lot faster, make no bones about the fact that it is a buggy proof of concept but lets people see the potential and get an idea for what the final product might look like.
