I don't think the author is really super familiar with some of those other organizations he mentions so he's reflecting how he thinks they work rather than how they work. That said the observations are still pretty good.

> You need to delegate execution authority to small teams who are aligned to a shared goal

It's been a while since I read the slides but this is basically what the author is advocating for and what doesn't tend to happen in dysfunctional organizations.

> Complexity management in organizations follows the same patterns as in code. Single responsibility, don’t repeat yourself too much, encapsulation, etc.

There are a lot of parallels. But organizations have people so that's an extra factor. You can't just "refactor" them without thinking about people's egos, objectives and such. So a lot of thought is needed into how to build effective organizations and sadly not enough thought is given is most companies.
