I forget if it was Samsung or Sony, but somewhere along the way on my internet journey, someone claimed, without evidence, and thus I have none either, that the incentive structure for having prestige jobs at large technology companies was always in hardware design and software was seen as easier and more low class.
So since nobody will get any promotions for running good software, they are not incentivized to run good software, and therefore they do just enough to get by?
Yes this is true and it might possibly be true for the rest of East Asia. Software is considered intangible and thus low value that anyone can do, whereas hardware is a real "thing" that you can hold in your hands, and is therefore more prestigious. Well, this way of thinking has made things into the current state.
This was and partly is the attitude you can find in german non-software businesses where software is gaining more and more influenxe. For example car manufacturing.
