The camera only changed the universe if we are in a simulation with lazy evaluation (things are extrapolated and created to be as they should exist when we look at them) or or if something like quantum superposition applies on a macro-level (the observed matter's state is changed based on our observation of it).
The camera didn't change the universe, it changed the *known* universe--made us a little less ignorant. For millenia mankind expanded its knowledge of places by travelling to them. That has now become prohibitive for almost every place in the known universe.
The easiest stuff is done. We still need to explore the oceans and the solar system, where travel is quite inefficient but not utterly prohibitive.
We also need to develop defense against world-killers. Biological, nuclear, and simple kinetic energy.
And the big hump after that should be interstellar exploration. Multigenerational, multicentury.
We'll need to figure out relatively stable world government and economy before that happens, so give us another four to twelve centuries, I'd say.
