In theory no, as whether a set is 'virtual' or
'real', it will still need to be designed. Most films do not have
Concept Designers, and all the design work is done by the Production
Designer, so all the sets that might now be virtual, would still
need to be designed in the same way as they have been for the last
60 years. Maybe there will be fewer carpenters and construction crew
on the film, and more digital modelers, but thankfully the
Production Designer's job will still be the same.
