Please show me this being used to debug a real program. Toy examples that don’t do any real work isn’t interesting. My confidence that this work for an actual program is approximately zero percent.

While I am not so negative, I'd also like to have a demo with a real example. Even if it does not scale, I think this could make debugging interesting at least for beginners and their smaller code bases. Rust is called a language that is hard for beginners, and I think every approach into easing things should be welcomed.

Let's stay positive here. This is very cool.

When it is objectively not a time travel debugger as prominently advertised, let us not stay mindlessly positive.

Hmm, one can be positive while bringing objectivity
