Oddly enough though, the analogy tends to diverge when scaled: the more material you put into your house, the less vulnerable it is; the more lines of code you put into your software, the more vulnerable it is.

Taken to an extreme, anyone can take down a house made of straw with their fist, but nobody can exploit hello world.

I despise seeing simple apps with ridiculous dependency trees (package.json with line counts in the 5-6 figures, for example) and other complexity that can't possibly be fully understood by whoever's responsible for operating it. But I suppose things would be in even worse shape if we reinvented the wheel instead of using well-known libraries and so forth.
