> It leads to inflexible systems which can't change, whereas loosely-coupled systems, which Linux has had until now, allow components to be easily swapped out and changed providing that the interfaces between the components are relatively well specified.

Wait, what? If you have a single large and totally integrated system, you can change what you want: everything is an implementation detail. If you have an infinitely modular system, you can't change anything, because every line of code is an interface.

I don't see your argument at all.

A highly coupled system is one where any part of it can interact with any other part of it, like a program written in assembly language, where every line of code is a potential jump destination. This makes changing parts rather difficult, as stated.

A loosely coupled one is just the opposite. In those all interactions happen through interfaces, so as long as the interfaces are respected, you can confidently change the parts behind them.
