This article gave me a new way to view tradeoffs. I never thought of things like a moving cycle between polarities but it makes total sense.

In the Google swe book, they discuss how search actually has 3 polarities (they didn't call it that, but I'm using your terminology here). So, do you think it's only ever 2 or can it be N?

That's a very interesting perspective! I have not thought of polarity systems with more than 2 poles but there's is no reason why not. It would still be a moving system cycling between multiple poles and might lean towards some more than others.

Maybe the usual "speed/ease/quality, pick 2" dynamic can be seen as a polarity!

Yes. What I particularly liked was how to capture the negative as well as the positive so we can get an idea of the state at the same time. (Side note: It's unfortunate our time at Google together was so short. But I'm thankful you are pursuing this adventure!)

Absolutely loved this one, great mental model. Never thought about it that way.

And great stories!

Thank you! It's definitely a mindset shift to think this way. Especially because we as engineers are taught to solve problems!

can upsides/downsides be more than 3?

Yep sure. You'll have some upsides and downsides between each pair of poles.
