deep learning is more important than rendering some random game.
And documentaries are more important than porn, but I think both of us know which one is the money maker as of right now. If you're short on cash and it makes money, you simply don't say no to it. They aren't mutually exclusive either. Neither do you say no to superb profit margins if you want to do expensive R&D. So what was your point again?
Besides, rendering some random games is what paved the road to HPC, deep learning, AI etc for Nvidia.
