I think that's where we are really headed. A combination of deep learning, boosted trees, svm, evolutionary algos, knowledge graphs e.t.c all stitched together to build stronger AI systems.
Remember our aeroplanes don't flap wings but still carry tonnes of weight and fly half way around the world. Once we discovered fundamentals of aerodynamics a lot of supernatural things were possible.
Same with intelligence, once we discover the essentials of intelligence and mathematically formulate it, supernatural intelligence is very possible. This is the thing that really scares people. I have no idea how close we are to it, but I'm sure it will change society the way internet and mobile phones changed the world.

Yes, we'll have GAs building CNN architectures, or a mix of several techniques, I'm enthusiastic for what the future holds
It will change the entire world the way humans changed the world. And that's scary.
Same for a deep decision tree (forest?). Or maybe a combination of several techniques, etc
A general pre-trained RL guided architecture search (#1) together with more choices of nonlinearity (#2), feature extraction (#3), pooling and memory argumentation (#4) and other tricks (#5) could be very powerful amongst many domains. Make it be able to accept multiple pre-trained models as priors and we're well on our way to general AI or at least a place where most data-scientists could be automated away.
(#1 deepmind had a demo a year back or so that was quite novel) (#2 vaguely remember someone training decision trees with gradient descent; could definitely see a 'randomforest' layer appearing in the middle of deep nets) (#3 just convolutions + tricks really). (#4 neural turing machine etc) (#5 any attention mechanism/any sequence mechanism (rnn/lstm etc)/ any graph relational understanding like the recent deepmind paper).
I also believe that researches have responsibility to outline the limits of their own algorithms in research papers. (For example, presenting examples that aren't recognized or data sets on which the approach doesn't work at all.) That is valuable information and they almost certainly have it at the time of publication.
