This is par for the course for HN; smart people failing to interpret a comment in a charitable light, preferring instead to author a condescending reply in an apparent effort to score imaginary points at the expense of intellectually stimulating conversation.
Turbofans being slow to spool up is jets 101.
So presumably OP never took jets 101. Neither have I. So what? The condescension remains unjustified and contrary to fruitful interaction. (See also the "lucky 10000" xkcd.)
Does any combustion engine, like the one in your car, have instant throttle response? When you hit the kickdown switch in your car there is still a delay before you start really accelerating. Now imagine a much bigger engine - it's not very difficult to guess one of those would take even longer without being familiar with the inner workings of turbine engines.
