Found an url of Joel Spolsky called The Law of Leaky Abstractions.
In short: we're busy with abstracting everything away, so we can get things done quicker and on a bigger scale. Negative: if something goes wrong, we'll have no knowledge of what is wrong and where it's wrong and it will take a tremendous amount of time to solve the problem.
This problem will get bigger and bigger as time (and abstractions) goes on.
