Those millions of dollars have already been spent. For example the P4 [1] language (a HDL language) and the Tofino 3 chip. It started out as FPGA (NetFPGA) to do programmable packet routing at linespeed. You now have the P4 language to define your packet routers with and generate your code. Ten years later we have 25 Tbps software defined packet routers.
