This is a legitimate question but this was clearly generated using an LLM. To add something constructive, this demo represents an amazing ideal of what debugging could be: [VIDEO]

Allan Blomquist's tooling demo they mention is incredible, go watch it: [VIDEO] Really sells the value of having a tight developer feedback loop: it shows hot reloading for code and graphics, a reversible debugger, live profiling with flame graphs, a data inspector with data breakpoints, time travel inspection with a scrub bar, session sharing and replay with the same scrub bar and direct links from the call stack to a breakpoint, and more. Above the many niggles they had with Rust itself, this greatly helps me understand why Rust left them wanting more from their working environment. They say they've switched back to Unity with [LINK] to try to capture some of that, and now I see why. (It's a shame that hot reloading tooling in Rust wasn't ready for them yet, but I see why they've moved on instead of waiting/contributing.)

> I should mention that the perfect debugger doesn’t exist It may not exist, but this demo has got to be the closest thing to the perfect debugger I've ever seen: [VIDEO]
