I've been a Swift/Obj-C engineer for my whole 15 year career. I now have all these odd jobs I have going on Raspberry Pis around my house that LLMs have written in Python. I'm now having them convert some of them to Rust and I am astonished on how fewer resources are used.
I let an LLM write a custom kernel for doing inference on an RPi cluster. The age of bespoke custom kernels is upon us.
I converted some Ruby stuff at a previous job to Rust pre-ai days and it was incredibly how much less memory they took and how fast it ran. But we still built everything else in Ruby because finding Rust devs was hard.
I am hopeful we can bring in an age of much more efficient software rather than fully prioritizing developer convenience.
