AI is a fantastic tool for exploring the field for a particular problem. If consider designs for a new shoe, I can run a batch that creates 1000 new and unique designs; some great, some terrible, some wacky – at this stage not production level ready but definitely useful for further ideation purposes.
This ideation process can also start from any existing piece of design, create endless amount of variations.
This technique doesn't work for every single imaginable design problem, but it does in surprisingly many domains.
