Yeah I dunno I just got it even though I didn't specifically ever look those things up. Just by osmosis I know what assembly looks like and I've heard of keyboard interrupts which... Don't those not exist anymore with USB devices or something?

You're correct. Modern keyboards have the CPU poll the keyboard rather than interrupting the CPU. Hardware interrupt really occurred with the old PS/2 keyboards, so this meme is technically outdated

Same, I don't even really know what assembly looked like (now I do I guess) but it just seemed like it was probably basic instructions, and knowing the meme is the yellow one interrupting the other and it would make sense that a keyboard would interrupt. Didn't even know ps/2 keyboards interrupting was a thing
