The newtonian physics part of flying a rocket is indeed the boring part of rocket science in these days of Ghz computing.
But all the engineering (an altogether different - if related - discipline) required is anything but simple.
And engineering and all of its sub-disciplines (materials science, propellant research, iterative refinement, operational research, logistics, 3d printing, computing, simulation, structural engineering, etc...) is both where the complexity lives and where the greatest progress in rocket science has been made.
Disagree.

The devil is in details, as usual.
