Can Physics Be Too Speculative? An Honest Opinion [Sabine Hossenfelder]

From the YouTube description:

I was asked to write an article addressing the question whether some research in physics has become too speculative. I did as I was asked, and all seemed fine, until someone on the editorial board of the magazine decided that physicists would be too upset about what I wrote.

The exact text of my opinion piece was too long to copy it here, so I put it up on my blog: http://backreaction.blogspot.com/2021/07/can-physics-be-too-speculative.html
