Imagine a blogger writing about some topic, and they have some ideas of concepts they want to find images that represent. It's possible to sift through tons of stock photography and maybe find one; but that takes a lot of time, and it sometimes ends with an expensive license cost.
Instead, with good prompting, you can not request a "photo" which matches your exact desires... close enough to perfectly that your audience won't notice or won't care about the last 1% that is imperfect.
And like the early days of online music, not only will people relax and accept imperfections (bad aliasing, mediocre sound quality), they may even become so accustomed to it that they will someday intentionally inject similar imperfections into creations so those feel more "natural" (comfortable based on the audiences' experiences).
