The game Roller Coaster Tycoon was famously hand written in raw CPU instructions (called assembly language). It’s only one step removed from writing literal ones and zeros. Normally computers are programmed using a human-friendly language which is then “compiled” into CPU instructions so that the humans don’t have to deal with the tedium and complication of writing CPU instructions.
To further emphasize this, I had an assembly course in university. During my first lab, the instructor told us to add a comment explaining what every line of assembly code did, because if we didn’t, we would forget what we wrote.
I listened to his advice, but one day I was in a rush, so I didn’t leave comments. I swear, I looked away from the computer for like 2 minutes, looked back, and had no idea what I wrote. I basically had to redo my work.
It is not that much better than reading 1s and 0s. In fact in that course, we spent a lot of time converting 1s and 0s (by hand) to assembly and back. Got pretty good at it, would never even think of writing a game. I would literally rather create my own compiler and programming language than write a game in assembly.
I’m probably completely insane and deranged, but I actually like assembly. With decent reverse engineering software like Ghidra, it’s not terribly difficult to understand the intent and operation of isolated functions.
Mnemonics for the amd64 AVX extensions can go the fuck right off a bridge, though. VCVTTPS2UQQ might as well be my hands rolling across a keyboard, not a truncated conversation from packed single precision floats into packed unsigned quadword integers.
petah please what’s this mean

To send the point home even more, this is how in python you make a line of text display:
print("Hello World")This is the same thing, in assembly (According to a blog I found. I can’t read this. I am not build better.)
org 0x100 ; .com files always start 256 bytes into the segment ; int 21h is going to want... mov dx, msg ; the address of or message in dx mov ah, 9 ; ah=9 - "print string" sub-function int 0x21 ; call dos services mov ah, 0x4c ; "terminate program" sub-function int 0x21 ; call dos services msg db 'Hello, World!', 0x0d, 0x0a, '$' ; $-terminated messageBut python turns that cute little line up top, into that mess at the bottom.
I like python. Python is cute. Anyone can read python.
Glory to you… abd your hoooouse!
