Anything human-orientated is going to need skill and time by the hierachy or organisation, and often on-going 'development' or relationship between people- one that modernism perhaps is trying to avoid than join together united.

The defaults of business often leans towards 'efficiency' which don't help always, often designing out these kinds of glue or interaction and only dealing with commands than decisions together or advices from 'lower' ranks. And keeping more people happy (or even no fighting) is more about working with happiness than efficiency - so shitty hardware that is plug in and play is often attempted not realising the whole evolution of communication and perfecting that (and being happy) is unavoidable! And it's what everyone has to do everywhere in the end. Replacing it with machines is often a future failure or bad short-cut for humans overall or for populations doing more machine-based interaction or time coding, more than anything else the whole day (time holes) thereby losing humanity or losing practice in humanity as time goes on.
Oh yeah we actually believe the adverts too like 'buy this computer and you'll do all this with it, which at the beginning wasn't really true, and maybe still things are hindered / problematic. We fall in love with the idea or new toy instead of getting to like people and getting as many people to help out as possible.

That's the short answer about;
- managing people
- needing more comms
- people needing maintenance themselves
- more cheap / expensive toys
- etc... but hope you got the basic idea. *wink*
