It doesn't say that global or stack variables will kill you, you're reading it wrong. Their problem was using excessive amounts of both, including corruption and accessing variables in very unsafe ways. There's nothing inherently wrong with either globals or stack space, and both are used heavily in even more critical software such as on space-grade parts.
