FPGA Chips For AI And Intelligent Cameras?

Are FPGAs rarely used in AI or intelligent cameras?
I've seen the news before that the Xilinx FPGA was used in the Megvii camera in China, and that the camera can achieve very high accuracy. It's been a while since, but there's no sign of widespread adoption of FPGAs. FPGAs can't compete with ASICs because of their cost competitiveness, but they can be designed flexibly. In other words, is my understanding correct that the functions required for analysis processors for AI cameras and intelligent cameras have already been decided and ASICs for these are now in mass production?
