This isn't to dispute that the benefits of an open office plan are fairly minuscule​ compared to the costs for most people, myself included.

I used to have to listen to white noise just to get away from the drip-drip torture of the endless prattle - my productivity at home used to be 5x compared to working in this open Hades.

I guess you are right - a lot of interaction will never come about if it isn't fostered organically by the environment. I am saying that in my case, what was fostered organically by the environment was people that first speak what they are about to type before typing it and utter every exclamation point associated with a failed `ls` or etc. It was Hades. I have ringing in my ears from listening to loud music and noise to drown out this aural rubbish and I can assure you that this ringing is a quintillion orders of magnitude more pleasant than the cacophony foisted on to me by the fine co-workers at this establishment, courtesy of the cage free office plan. I left as soon as I could and while I miss the money/benefits, I don't miss the noise - not one little bit.

About the noise pollution...

Like decision fatique, I think we all have a stimulation budget (buffer). Most of the time, I'm fine. Until I'm not. And my budget (buffer) gets smaller as I age.

Nowadays, I'm completely content to be facing a wall, with earbuds in, so I can tune out and get some real work done.

While it's definitely distracting, there is a type of conversation that occurs which I have never experienced in all my years as a cube farmer. If I want isolation, I can go sit somewhere else or work from home or a cafe. It feels like the default being not isolation makes all the difference.

You're lucky, I can't. I agree that an open office has its benefits but when you can't treat its downsides with the methods you stipulate then I don't feel it's worth it on balance. I'm forever distracted and even just the cubicle farm (not fully sealed offices) was a much better environment for me.

Yea for those whose work requires some concentration, the best environment might be where workers have offices with open areas available to them when they want to discuss issues with other team members. It is very sad that companies can't be flexible in this area and instead like to pretend that only upper management needs to concentrate, have a private conversation, etc.

Then my boss stuffed some clowns onto my budget and ruined the magic.

Since then, most places I've worked have been either call centers or highschool cafeterias. No amount of bon ami can overcome inhumane working conditions.

I'd rather have an office.
