There will never be a vibecoded Photoshop.

For Photoshop there are already "competitors", such as Canva or GIMP or countless others. But adoption has been limited.

Why ?

Because of the tightknit Adobe integration. If I create something in Photoshop, I can pull it in natively into any other programme in the Adobe suite ... e.g. InDesign (desktop publishing), Indesign (vector illutration), Premiere (non-linear video editing) or After Effects (motion graphics).

Not only can I pull it in natively, but in most cases I benefit from Adobe Dynamic Linking. Which means if I go back and mess with the Phtoshop file, it is automagically updated in all my child projects elsewhere.

Do not underestimate the sheer boost to the workflow and time savings that that provides !

Building on the above, if I'm recruiting designers, there is a very high chance they've spent the last 20 years using Photoshop. Am I going to waste my time and theirs forcing them to learn GIMP or whatever ? No. I will just get them an Adobe license.

Now let's hypothesize that my theoretical designer that I just employed has produced a product in InDesign that we're sending off to the printers....

If you want to get the best out of your printer during the pre-flight process, then you're absolutely want to be sending them a PDF file that came out of the Adobe toolset. Why ? Because your printer can send you Adobe-ready preflight-validation config files and because your printer can help you with issues. Not using Adobe ? Prepare for your printer to say "on your own chum".

Adobe is not perfect, but they command the market dominance they do for very good reason.
