if it hasn't even flown yet? All kinds of changes can be made to the aircraft in the meantime, so we don't know if all the promised avionics or armaments (can they be procured in sufficient amounts?) are going to show up by then or if this is the sort of hyperbole and overselling that often comes out of YouTube commentators. I don't know why you said the "author makes a strong argument" when there is very little evidence regarding what the future LCA Mk II will have compared with the existing J-10C. Regardless of how "good" the radar/missiles are (I won't comment on RCS because that is secret, influenced by whatever RAM coating is applied, and neither plane was designed for low RCS in the first place), I suspect Indian aero industry will have problems manufacturing at large enough scale to meet IAF needs in the near future, while production of all J-10 variants is ramping down in favour of J-20.
