He’s talking about how the brazed piping on the nozzle, used for regenerative cooling is outdated; because most rocket nozzles now use internal channels in the bell for cooling, due to modern improvements in machining technology. The nozzles of rocket engines with brazed bells like the RS-25, F-1 and RL-10s were and still are hand-made, making the process expensive. Personally I like the look of brazed nozzles, their ribbed for extra pleasure in my mind.
