There are two stages to becoming a decent programmer: first you learn to use abstraction, then you learn when not to use abstraction.

Trying to find the right level is the art. Once you learn the tools of the trade and can do abstraction, it's natural to want to abstract everything. Most programmers go through such a phase. But sometimes things really are distinct and trying to find an abstraction that does both will never be satisfactory.

When building a house there are generally a few distinct trades that do the work: bricklayers, joiners, plumbers, electricians etc. You could try to abstract them all: it's all just joining stuff together isn't it? But something would be lost. The dangers of working with electricity are completely different to working with bricks. On the other hand, if people were too specialised it wouldn't work either. You wouldn't expect a whole gang of electricians, one who can only do lighting, one who can only do sockets, one who can only do wiring etc. After centuries of experience we've found a few trades that work well together.

So, yes, it's all just abstraction, but you can go too far.
