IMHO assembly isn’t hard. When you gain enough experience you start to see „visual patterns“ in your code. For example jumping over some lines often equals to a if/else statement or jumping back is often a loop etc. Then you are able to skim code without the necessity to read each line.

The most difficult part is to keep track of the big picture because it is so verbose. Otherwise it’s a handful or two of instructions you use 90+% of the time.

I needed it often in the past in the PLC world but it is dying out slowly. Nonetheless, when I encounter 30+ year old software I’m happy to be able to get along. And your experience transitions to other architectures like changing from one higher language to another.

Nonetheless, if I’m able to choose, I’ll take Go. Please and thank you 😊
