I think it's realistic to expect this to be the work of decades! Great talk by Bjarne.

Will attrition make a decades-long timeline viable? I'd never touch C++ myself, I'm too scared there will be a long period of time where I'd be actively dangerous and introduce security holes. I am learning Rust, because that type of low-level systems programming seems like a valuable thing to have.

Are there young devs who aspire to go through the C++ learning curve? I'd love to hear about your experience!
