Your perspective might be why I enjoy microcontroller work. I love getting to know everything about the system, reading hardware documentation, and getting the low level parts to work in a highly deterministic way.
I use ATTiny85 cores when a ESP32 costs almost the same, but the 85 only has 256 bytes of SRAM and five I/O pins so I can track it all and ensure it will do exactly what I want.
