  1. 47:30 I think "Would you switch to typescript if introducing this new syntax would allow it to run 100x faster than javascript?" would be even closer analogy. And even I would stop writing vanilla JavaScript if TypeScript were actually faster.

  2. From the official Mojo manual: "Mojo uses a third approach called “ownership” that relies on a collection of rules that programmers must follow when passing values. The rules ensure there is only one “owner” for each chunk of memory at a time, and that the memory is deallocated accordingly. In this way, Mojo automatically allocates and deallocates heap memory for you, but it does so in a way that’s deterministic and safe from errors such as use-after-free, double-free and memory leaks. Plus, it does so with a very low performance overhead." So it's much closer to Rust than Java or J# or JS.

  3. 20:30 I see this as argument that is logically "I don't like the syntax of Rust" and the implicit case (without "&" or "owned" or "^") should be different than it's for Rust. That is, skill issue. That said, Mojo seems to have lots of good ideas so it's definitely yet another language worth learning.
