Edit: And the irony of this -> Only ASICs will survive.
No. We'll see adaptive algos introduced which favor FPGA's. While FPGA programming may be a specialized skill and it takes time to code up a new algo, the cost and time to market of a FPGA solution will always be a lot less than designing and deploying new ASIC solutions and their energy efficiency (operational cost) will always be better than gpus.
Personally, I think there is no reason why fpgas can't be game changers.
