I am kind of sad such smart people on here are missing the forest for the trees. Moving institutions, historically, is about cross pollination of ideas. In physics this has been important because different institutions provide variations of how to 'think like a physicist'. On top of that, it allows for a mixing pot of lab culture and best practices. They even did a good job of pointing at this in the movie Oppenheimer, where he visits Germany and has a formative experience which changes the trajectory of his focus. It's very easy to 'do it by the numbers' and be repetitive in your work when you stay in the same institution. This is also the reason why 'sabbaticals' are still a thing, so professors will visit for a 0.5-1yr another institution or research hub for their field, which in theory happens every 7-10 years if the professor takes advantage of it.
