Yeah 6 months ago Claude could make me a rust function that wouldn't compile but got me pointed in the right direction. Now it will make it correct with comments and unit tests with idiomatic style just using chat. But we don't have to use chat. Even open models today like devstral when combined with an agent can run cargo check and clippy and self prompt (with rusts great error messages) to fix everything. Prompting it with some unit test cases lets it iterate until those pass too. Software development has fundamentally changed. I still would advise developers who care about performance to be able to read asm. But just like I wouldn't write asm anymore, because the llvm optimiser is really good, we are going to get to a point where designing the test cases will be the same as developing the software.
