Human is not the most important things in the universe. It is necessary to avoid the idea that it is the most important things in universe. However, business is not the most important things in the universe either. Love of money is the root of all evil. Also, it is not quite clear to me what "human centred design" is meaning, exactly. I can also comment about the first paragraph: Much of the newer software isn't actually that good user interfaces design, and also omits stuff that is good to have, and if the user has not read the instructions then they may easily make a mistake that is their own mistake, I think. (I think the better design is you have enough ropes to hang yourself, and also a few more just in case. It should not stop the user to do a stupid thing because then it prevents a good thing from being done, also.)
