The channel program concept described here, where I/O operations are offloaded to a dedicated controller with its own instruction sequence, was a structural ancestor of modern asynchronous I/O and DMA architectures. The System/360 also codified the byte as exactly eight bits, a decision so foundational that it became the silent assumption underlying every computing architecture that followed.

Hairstyles used to be better than they are today.

Amazingly, IBM is still making videos like this. You can find great videos online from them explaining the technical details of LLMs, ML, and the like [1]. The guy in this IBM clip is a progenitor of what they still do today.

I've worked most of my career in developer relations at various Big Tech (advocate, evangelist, pre-sales, etc.) which in large part entails giving presentations explaining how a company's technology works to others. It makes me wonder if the couple official company videos I've made will be viewed in 70 years by that generation's techies.
