It's a symptom of success. Physics has done a good job of modeling
everything within the scope of experiment and observation. So now
extending theories means going beyond what's testable; i.e. speculation.

Over the past few decades there is an explosion of people who think
the "mathiest" math will help in advancing physics.
This is a typical example:
*Modern Physics formalized in Modal Homotopy Type Theory*

There are many other examples based on many other areas of advanced
mathematics.
None of this stuff helps in understanding nature - supposedly what
physics is about, or is any way useful in using physics in real
applications (technology).
It can all be interesting pure mathematics, but actually worthless.
Actually it's worse than worthless, It suggests nature (or rather, the
best code of nature we have so far) is this stuff.
