I think FPGAs are not like general purpose MCUs. I think the comparision is like between CPU and GPU. GPUs are fantastic at solving some of the problems but you don't see people rushing to use GPUs in every computing application. Chances are, if you can implement it on MCU you will want to implement it on MCU because: 1) you need an MCU anyway either separate or FPGA based one 2) FPGA programming is sucha a hassle and not because of the tools but because it is genuinely hard 3) learning FPGA development well is a major effort as it requires different type of thinking. It is much more of a change that going from one programming language to another as entire concept of what is a program changes. 4) if you need more power, it is typically easier to step to more powerful MCU than to FPGA. As I understand, we need some number of very specialized people that can invest the time to learn hardware design on FPGA and the rest is better off spending that time thinking of fun MCU-based projects:)
