'reality is subjective, a construct' is one philosophical stance, but by no means the only one possible I'm not so sure about that. I find Kant is pretty convincing; scientific realism is pretty vulnerable when faced with the fact that theories change. Science is best viewed with an instrumentalist perspective, that's where it is most solid. We simply don't know if we're brains in vats, or creatures in a simulation. The real reality is unknowable.
