No, AI makes it easier to get boring ideas to more than an elevator pitch or "Wouldn't it be cool..". Countless people right now are able to get that initial bit of excitement over an idea and instead of a little groundwork on various aspects of it.

That process is often long enough to think things through a bit and even have "so what are you working on?" conversations with a friend or colleague that shakes out the mediocre or bad, and either refines things or makes you toss the idea.
