Fly-by-optics is simply a next evolution of fly-by-wire, replacing electric cables with optic cables. It's not that big of a technological leap. In addition, huzhigeng already mentioned J-20 will feature the largest radar (in terms of dimensions) amongst all 4th gens.100 KW = 135.96 HP
I watched the video. The report is highly unreliable since it mentioned something like "optical fly by wire" or "fly-by optics". I honestly do not believe J-20 is that advanced.
Also, think of the air conditioning needed to cool down a 100kw AESA radar?
