For sure, but there are all kinds of bad photoshops out there where it is super easy to tell, much like bad AI images that stick out like a sore thumb (or 2 thumbs).
But getting good at photoshop takes a lot of effort (as well as a license or a will to use it otherwise), that will remain the same. The same can't necessarily be said for AI images which have been improving year over year and becoming more and more accessible.
But anyone could have already paid someone who is decent enough at photoshop to make a convincing edited photo. It's not like you yourself needed to be good at photoshop for it to poison any image that someone wanted.
People could previously have afforded to get that done for any specific image, but now it's now possible for a propagandist to give each and every resident of the USA their own personalised faked image for a total cost of about $25k (if their electricity costs $0.1/kWh).
