Making comics about software engineering stuff is a really good idea. I love this, its very charming. As someone who likes drawing and is an SE I'm sort of inspired.
What is left out is that Project MAC was ridiculously ambitious. As in, most operating systems, and probably all multiuser/interactive ones, have Multics in the "tree of inventions" behind them.
The issue is that Bell Labs wanted something smaller and more immediately usable and ultimately they got it by accident because few programmers had seen the future and started to miss it.
