Lord, Amara is a luddite at heart! (byegones...)

Ok, we can negotiate on this. We will give you Pluto but will
dismantle Charon. Ok?

No argument. But it begs the issue of when precisely simulation
will trump obsservation? At some point observational astronomy
will have to give ground to simulation based astronomy as the
simulations demonstrate increasing accuracy.

If I can run a complete (and accurate) simulation of whether
Europa could have evolved life then isn't it rather pointless
to send a probe there?

It fundamentally comes down to a cost issue -- whether the
simulation can bootstrap itself into a reasonable prediction
of the outcome vs. running a real-life experiment based
on real molecules in planetary quantities. Its a numbers
game -- sooner or later we have to live with it.
