> However, the "problem" is why ~125GeV. If there are extremely high energy particles (which are expected in a Grand Unified Theory), then corrections to the Higgs mass would be enormous. This is a fine tuning problem where we arbitrarily tweak those corrections such that we magically end up at 125GeV.

When I was undergraduate at CERN summer school program I got that this was one of main themes to justify existence of SUSY. However I am still puzzled even after having obtained a PhD (condensed matter) how does this arbitrary tweaking of corrections does look like.

Is it simply unwillingness to accept for world as we live know some parameters of the world like particles masses are not that independent from each other?

There are other problems with the theory too, they probably weren't solved perfectly by whatever SUSY model your supervisor was working on so they got less attention.

But ultimately, yes. The entirety of modern physics is largely borne out of the unwillingness to accept the the world is simply as it appears and that there's no deeper unifying principles.

Based on what I understood from Sabine Hossenfelder's writing, yes, that is a big chunk of modern physics. One example is "the naturalness problem", that some base parameters of the SM are orders of magnitude larger or smaller than other ones - which is of course entirely possible as a fact of nature.
