> everything run magically leaner and faster

In my opinion, there's no magic in the software engineering. Everything (or almost everything) is a system that can be described, explained, modified and so on. Applications, libraries, operating systems, kernels, CPUs/RAM/GPU/NPU/xPU/whatever silicon there is, ALUs/etc, transistors, electricity, physics... That's nowhere near "magic". There's always some trade-offs, it's just that you may not be aware of them initially.
