Okay, but genuinely in what cases the borrow checker caused issues for you? Cause I use Rust for a few years now and have not yet encountered the infamous fight with the borrow checker.
Also, there’s a “new” and “better” borrow checker coming in 2024 edition.
Wireless communications radiation physically cannot cause increased mutation rates and this is quite well studied. Wireless communication operates on frequencies (for the most part) below 10GHz, which has wavelengths measured in centimeters and meters. The biggest wave that can impact human DNA is UV which has wavelengths measured in nanometers - orders of magnitude of difference. So no, wireless communications are super unlikely to impact cancer rates.
