What are you talking about? > HFT firms have been banging on the drum of making FPGA's infinity programmable for a decade That's strange, because FPGAs have been infinitely reprogrammable for longer than that. > lots of commercial FPGA's can be re-flashed now That's even stranger, because the vast majority of commercial FPGAs are not flash-based, but SRAM-based and can be reprogrammed as often as the registers in your CPU. Besides, HFT firms would be using SRAM-based FPGAs because they are faster and larger than flash-based ones, the advantages of flash-based ones are useless to them. > "what has HFT actually done for the world" Well, not this, that's for sure.
