You see that in RF design where tech is developed with software defined radios, then moved to FPGA's/Gate Arrays, and then custom silicon. And the power requirements drop by 95% each step.
Also microprocessor manufacturers have always pushed back against specialized coprocessors as much as they can. Apple bringing it all in house allows them to nullify that impediment.
Custom Silicon -> Programmable Logic --------------> Software.
