I don't quite agree with you saying it's impossible to create professional and useful images from a text description.

I have been following the AI image generators for months now and I can assure you the progress is very, very fast. As AI continues to evolve, it will become increasingly difficult to tell the difference between art created by humans and art created by machines.

I have published articles about a few notable AI models which are comparable if not better than Dall-E2. You should check out Google Imagen and Stable Difussion.
