I'm no expert, but I've been hacking in Rust for several years now, and the only unsafe I've written was required as part of building a safe interface over some hardware peripherals. Exactly as intended.
The borrow checker is something new Rust devs struggle with for a couple months, as they learn, then the rules are internalized and the code gets written just like any other language. I think new devs only struggle with the borrow checker because everyone has internalized the C memory model for the last 50 years. In another 50, everyone will be unlearning Rust for whatever replaces it.
