Yes, the controls of an excavator look very complex, but it is a one-to-one interface. There is exactly one control for each type of movement and it does not have any 'options' attached to it. There are no levers on levers that make the lever just work a little different. I am getting the impression that this is not the case with git. Sometimes there are multiple ways to get something done. Often you have to use several git command to achieve a certain effect. There are several modes of working with git. I some modes of working, using 'git rebase' should be avoided at all costs. In another mode of working, it is almost mandatory to use it. Git is like a toolbox with a large collection of elementary tools, where it is often the case you have to use some of the tools in a very strict order to achieve a certain results. This gives you a lot of flexibility, but also room to a lot of errors. I can imagine that some people prefer a less flexible toolbox, where each tool performs some complex combination of elementary tools, but where there is much less room for errors. Also see:
