I wouldn’t say so.
One of the advantages I find for stock sites is finding similar style images or charts/graphs/infographics for use of quicking interchanging the data.
For example, I might find a particular style of graph to be interesting and I then search for your name and other graphs you might produce and use those and interchange the data.
I don’t have to spend hours constructing graphics when it’s already done for me.
Finding similar style graphics for a publication is a challenge and there’s a huge advantage to finding a style that suits and everyone agrees on which makes it easy to use for publications.
With AI you might be able to get a 90% type of image created that you think looks good - but it requires that extra.
Here we fall into untrained eyes scenario - where the person creating an AI image might go - hey this looks really good.
But working with an artist or with a designer gives the opportunity for feedback and improvement and more detailed experience.
I think AI is here and we need to embrace it. Once more as an imaginative tool like any software.
Have you considered using it yourself to generate assets for stock sites?
Could it speed up your workflow?
You could alter the image and make it ready - and how would they know if it was AI-generated or not?
Could you take a style of some icons and ask AI to generate more versions in a similar style - fine tune them and upload?
