He's talking about human-computer interaction paradigms, not computing paradigms. He's not a general computing expert, he's a UI/UX expert.

"Batch computing" in this context refers to the era of punch cards, needing to wait for results overnight, and the difficulty of editing pre-existing programs -- and how all of that utterly dictated the style of interaction one had with computers.
