A chainsaw is not safe. But you can learn to use it safely.

Replace chainsaw with:

  - knife
  - guns
  - C programming language

There are tools and methods (and a lot of discipline) to ensure safety in C:

  - compiler's sanitizers[0]:
    - address: to detect out-of-bounds and use-after-free bugs
    - pointer-compare, pointer-subtract: to detect invalid operation when pointers are non null
    - shadow-call-stack: to detect return address overwrites (stack buffer overflows)
    - thread: to detect data races
    - leak: to detect memory leaks
    - undefined: to detect undefined behaviors
    - ...
  - static analysis tools, like Splint[1]

Would you ride a motorbike without the proper protections (helmet, heavy jacket, ...) ?
