As others have said, I suspect you've just grown accustomed to its quirks and defects and learned to work around them. For example... * always refresh X before doing Y. * if you see this signing error, clear this cache. * don't try to drag this file here because it gets linked in the wrong way ...and so on.
If you were able to use a magical, fast, bug-fixed, version where everything 'just worked' at pace, I imagine you would begin to realise just how much you have been putting up with!
