I thought languages such as Rust and flamegraphs and etc were supposed to help us avoid doing all this testing and optimization right? Like I use the built in analysis tools that come with cargo and such and what I have on my os, tools like cutter or reverse engineering tools. Even on python I use the default or standard profiling and optimization tools, I wonder sometimes if I am not doing something enough if the default tools thats recommended should cover most edge cases and performance cases right?

heck even the ai by default doesnt start with security from the models I have tested its really really weird.
