FPGAs have never made sense. They're way too expensive to use in volume. There's no practical use case for "cool, I can reprogram the chip in the field to implement different functionality". Nobody has figured out how to usefully integrate them with a CPU to make a low-volume SOC. CPUs became so fast that most applications don't need customer hardware. Regular gate arrays are cheaper and faster above minimal volume.
They seem to only have been useful for prototyping and military applications (low volume and infinite budget).
