Starting from main isn't actually a good way to explain a program almost ever, unless the program is trivial.

His point is that a lot of software design has failed to be even as good as print design--that software design really has focused so much on interaction, we kind of treat the computer as this machine that we need to manipulate and less about displaying information--for people to make decisions, to come to conclusions, to learn something--and that by focusing so much on interaction design, by focusing so much on the computer as a mechanical thing, we've really made bad software.

And so he wants to say part of the problem here is that the people who design can't make these context-sensitive magic ink--right? It's like: print design but now it knows something about your context. And so designers really aren't able to make these rich information things that are dynamic but not interactive. And so you could really kind of call this "Interaction Considered Harmful", and the idea is that our software should only be interactive when it has to be and really our software should be context-aware, good, print-like displays of information.
