The industry has definitely evolved in the past 10 years! From my observations, since I started working professionally in the archviz from 2007 til now, the industry is branching off into 2-3 completely separate paths.
In my opinion, there will be always a need for photoreal Real-Estate imagery that cannot be replaced by realtime or lumion software. Because in real estate, we are selling the lifestyle, the clients prefer more emotional, story telling images that can sell you the house, so the main hero in this branch is the image. The image that will be printed on billboards, magazines and displayed on the websites. The extra gimmicks (AR, VR, animation) are extras that might not have the same effect as the main selling image. For this extra gimmicks, I think there will be a specialized field, so the client might even outsource to another company and give the stills to another.
So far we have two very related branches, that can still be separated:
Branch one - Real Estate (highly specialized on stills to sell the lifestyle)
Branch two - AR/VR/Animation (company that provides the extra gimmicks)
The third branch - is the situation that you have mentioned regarding architects and designers using new quick software such as Lumion to speed up their designing process. The quality of Lumion has greatly improved in recent years, but it still far from high quality real-estate imagery... and I do not think it can ever claim that field, it is not specialized in that direction.
I am sorry to say that, but I think the third branch is going to be a bit hard for the archviz artist to survive in...because if all the architects can do good enough visuals and if a company only needs this kind of level, then why the need for the archviz person? Of-course if the company is big enough it will always have an archviz department, because thats what big companies do. However, for midsize and smaller architectural firms I think archviz artist will be an extinct creature.
PS: By the way, hand drawing is making a comeback, I see more and more renderings that are a mix of sketchup + hand drawing. I think this is some kind of an exotic archviz trend that only a few will be able to specialize and make quite a nice income!
