And I have a really good feeling that this will be the year that humanity finally gains the upper hand in our millennial struggle against the Arctic ice cap. Once the ice cap melts completely, even temporally, it will shift the equilibrium of seasonal oscillations. Every winter it will freeze a little less; every summer it will thaw a little sooner. Until our final victory is inevitable. Congratulations everyone. And keep up the good work.
Heck, all of physics we know can be simulated even in a classical computer, they are just differential equations
Spoken like someone who has never actually tried to simulate those differential equations for an non-trivial problem. Those simple equations, like the Schrodinger equation, become mathematically intractable as soon as you simulate something more complex than a hydrogen atom.
So you're making the same argument as Intelligent Design advocates. You're saying that because an artist can paint a realistic representation of a sunset, that the real sunset must have been "painted" by an artist too.
it is very likely that an advanced civilization would have the ability to run very accurate simulations
That is an unfounded assumption. You're taking a mere 50 years of computational progress and extrapolating to infinity. But there are physical limitations to computational density and mathematically intractable problems (like the many-body problem) that don't go away no matter how many iterations of Moore's law that you throw at them. Even simple, well-defined sets of differential equations, like the Navier–Stokes equations, are a struggle to simulate.
