I&#x27;m in string theory as well, most of my knowledge about LQG is mostly from other string theorists. From my experience, string theorists can be extremely hostile towards the ideas in LQG and the people involved in it. So I would not quite share your view.<p>Then from LQG there is for example this [0], which portrays string theorists as a bit naive and ignorant.<p>I know that LQG is not purely focused on quantum gravity, there are some papers out there that discuss how to combine Yang-Mills theories to LQG, and it is suppose to be &quot;easy&quot; (see discussion around page 15 of [0] for example). But, as you might mean when you say that they are purely focused on QG, is that it is (or seems to be (to my very limited understanding of LQG)) to some degree considered a solved problem.<p>[0]
