Basically, the problem is input, but AFAIK a lot of AIs now are multi modal. Yes they can make up stuff but if you steer it to the right direction with proper context or inputs, it can help build. Maybe what you're talking about is AIs can't choose rather than think. They can think. Albeit, they can't choose only because of the guardrails. So, you are the user chooses to steer it to what you want
