If you’re making very low end HW maybe this is true. Because HW is something that you put into the real world there are other constraints such as power, cooling, space, security of supply, ability to ramp, cost, reliability, etc. The calculus for HW selection is much more involved than simply SW. Good SW/FW can be performant on much less capable HW but it does mean that SW engineers need to understand more about the HW. This is a very rare skill in 2025. Most SW engineers I’ve encountered cannot explain stack vs heap. Furthermore even fewer understand how to use malloc correctly.
