The same way Wordpress obviates the need for web devs.
> DALLE is to artists what self-driving cars are to truckers.
Always 10 years away from replacing them?
Wix and Squarespace (the spiritual successors to Wordpress) however have undoubtedly put lots (most?) contract WebDevs out of business. There are still plenty around - go check Fiverr or UpWork. However it's impossible to argue that these tools haven't made it easier for non-web devs to build a fully-featured and beautiful site for a fraction of the cost in a fraction of the time. It used to be that these no-code site builders all looked crappy and cookie cutter but in the past few years they've really upped the quality of their templates such that they often are indistinguishable from a "handmade" landing page.
I think the path is likely to be similar for these AI image and text generators.
Devs had to step up to create something better than Wordpress to stay on the market.
The same way, artists have now to create something better than DALL-E results.
