No, You Can’t Manufacture That Like Apple Does
It's pretty much the same in software too.  I often get requests for functionality and when I say "no, we can't do that", I get "Why not?  Amazon does it".Hrmm... Amazon has dozens of people working and supporting just that one feature.  You're trying to engage me to do an entire project.  On a fixed budget.  With a fixed time frame.  And you've changed your mind 3 times in the last 3 weeks on key points.Of course, yes, there are amazing things you can do with software that weren't remotely feasible even just 5 years ago.  But there's always a moving target - the market leaders (Apple, Google, Amazon, etc) are constantly pushing the boundaries of what's considered 'normal', and most people have 0 idea of the real cost and effort involved in having the functionality come across as polished and error free as the big boys.
