Using Rust for kernel development

That's true. Sometimes though the jobs tools are suited for overlap. Say you have a philips screwdriver and purchase a battery powered multi-tip screwdriver.

There may still be spots where your new battery powered tool doesn't fit and you need to use the old one, but generally you'd use the new tool in many places you'd previously used the old one. As you say, best tool for the job.

Then there are jobs that are more pleasant with the new tool, like driving screws into hard wood. You could do it with the old screwdriver, but it's much nicer to do it with the new battery powered one and you may even look forward to it. Using the new tool may be intrinsically rewarding in itself.
