Depending on how many shortcuts you take and how much resources you have, it could.
If it's naïevely rendered, 66 seconds times 30fps is 1800 frames, 10 minutes rendering per frame, 12 days. This scene is very simple, so I think 10 minutes is a bit much, but in any case it's not an unreasonable statement.
(The scene is so simple I feel that with PBR and some fancy postprocessing you could come very close in real time even without their RTX tech.)
