I've used Rust quite a bit, but I would love to hear more about this. Is this comparing to lower level languages like C/C++/Zig, or higher level GC'd languages? What problems does it make us think more about up-front, and do you think it's due to single ownership (in the C++ and Rust sense) or the borrow checker?

If you think about programming as information transformation (ie: you are getting information in, applying a certain transformation and then giving some output), programming becomes about how this information flows. Data structure becomes the most important thing.

Here is an example that now frustrates me about JavaScript. I don't know if some variables "MyVal" declared somewhere is global, local or how transfer it around. Global variables no longer makes sense to me. In Rust, global variables are possible but they are obvious and their scope is completely within your control. Now, all the data is there and it's up to you how to structure it, move it around, store it, etc.. You have to think these through before doing any code. If you don't think well enough, the Rust compiler (borrow/ownership thing) will start to give you headaches.
