First, Moore’s Law and computing trends indicate that more and more things will be parallelized. Deep Learning will exploit that.
Second, the AI singularity is predicted to happen in 2029 according to Ray Kurtzweil. Advancing Deep Learning research is a way to get there to reap the rewards and do good.
Third, data doesn’t sleep. More and more data is accumulated every day. Deep Learning will exploit that.
Finally, deep learning is about intelligence. It is about technology, it is about the brain, it is about learning, it is about what defines humans compared to all previous species: their intelligence. Curious people will know their way around deep learning.
