I think It will go up at least in next 10 years. The whole architecture may not have change, but the detail will change simultaneously with advances in brain study because it is biologically inspired.I think deep learning is a concept and does not refer to any specific techniques. Any network with many layers is called deep learning.
This is a bit outdated but provides input on future trend, as suggested by top researches in deep learning as of 2015.Any similar link with more updated version will be better, but for now, here is the link: https://www.kdnuggets.com/2016/01/deep-learning-2016-beyond.html
