Privacy is an illusion for most people, and in office spaces, it's also a red herring. Wifi trilateration doesn't make things worse when you have a CCTV camera on every corner, badge reader at every other door, and presence sensing in conference rooms. Dystopia does not materialize without a severe regime shift.
Nah, my main worry is precisely sustainability and optimization, i.e. cost-cutting, because the more tools you give a business to optimize, and the more bullshit excuses ("sustainability! saving the planet!") you give a business, the worse the outcome is for users (here: employees). And a lot of that is doubly annoying, because it's counter-productive.
So what you have smart sensors in every room, and combine it with badge readers and wifi trilat and what not, and have smart auto-routing/rebooking algorithm: half the week, all conference rooms are always booked full, and yet somehow when you physically go and check, a good half sits empty, and it's apparently an impossible problem to solve.
So what the bathroom wall says, "with water-saving fixtures, we're using much less water in this building", and "we're now saving 2L water per flush". It's all bullshit, because those eco inventions mean I need to flush 3 times instead of once, and it means that I spend a minute washing my hands instead of 10 seconds - especially because both the soap and the dispenser are also optimized, so it takes 20 seconds to get enough soap on your hands, and then extra 20 seconds to get it off afterwards, because unlike normal people soap, it leaves your hands slippery for some reason.
And then they say "scientists said you can dry your hands with just 2 paper towels". At that point I'm getting red, because yes, I saw that TED talk 15 years ago too, and yes, it's total bullshit. Maybe it was true then, but the industry and the beancounters have value-optimized paper towels 15 times since that.
The generalization and summary of this rant is: slack is good. Happiness lives in slack. There is such thing as optimizing too much. Also the small, isolated systems under optimization, are in reality neither small nor isolated.
