The dialetic beings with OP, and has pcw's reply and then mine. It does not begin with pcw's comment. The OP complains about rust not because they imagine Jai is memory safe, but because they feel the rewards of its approach significantly outweight the costs of Rust.

pcw's comment was about tradeoffs programmers are willing to make -- and paints the picture more black-and-white than the reality; and more black and white than OP.
