The danger of tools like this is eliminating those margins. This type of automation will eliminate junior graphic designer roles and add new requirements for the experienced graphic designers. Both of these affect the job market by making it harder to get started and stay. There will always be the high end and boutique jobs. The picassos and rembrandts will continue to find work.
The starving artist who sells out to create ads or create content for commercial entities will find those opportunities dried up
A single agency using this tool effectively could "in theory" produce 500 times the artistic output from a single artist. Vastly shrinking the market for a decent paying career.
