The kind of commercial photography that deals with new products might not exist in the foreseeable future. Already, we see a lot of CGI where we would have expected photography to generate the images. CGI now renders potato chip packets, electronic devices, cars, and goodness knows what else. I've already written about CGI models and this kind of thing before. But a lot of CGI tools are becoming democratised. E.g Unreal Engine 5. You can't put the cat back in the bag. If you just started out as a commercial photographer, maybe start learning UE and Blender. Personally I am a documentarian (e.g. portraits) so that stuff is not relevant to my specialty. But, the days of commercial photo studios (and their often extortionate prices) are going to come to a close. I don't think this shift will happen for a few years yet, but I sense that it is coming. Your clients won't cry for you, so take this seriously. Just know that CGI can do almost anything - although it doesn't mimic movement very well yet. You can model entire cities in software. CGI models don't turn up late, and in software, you can have infinite DOF, infinitesimal DOF, or anything in between. Make of all this what you will.
