Another commenter mentioned Topaz AI upscaling, and Pixelmator has the "ML Super Resolution" feature; both work remarkably well IMO. There are a number of drop-in and system default resolution enhancement processes that work in a pinch, but the quality is lacking compared to the commercial solutions. There are still some areas where DALL-E 2 is lacking in realism, but anyone handy with photo editing tools could amend those shortcomings fairly quickly.

On-demand stock photo generation probably is the next step, particularly when combined with other free media services (Unsplash immediately comes to mind). Simply choose a "look" or base image, add contextual details, and out pops a 1 of 1 stock photo at a fraction of the cost of standard licensing. It'll be very exciting seeing what new products/services will make use of the DALL-E API, how and where they integrate with other APIs, use cases, value adds like upscaling and formatting, etc.
