I like the old times when you could assume everyone around you is smarter than you, so collaboration and communication were never an issue. They never rely on "experts" in other teams to collaborate, they quickly and easily pick up how other systems work in depth themselves. Smart people just shine and work together to create amazing stuff.

Nowadays, you need to explain to people why unit test is needed, why you can't use production as the first place to try a risky experiment, and rely on 20 experts, one in each tiny service, to figure out and to deliver a tiny feature with bloated timeline and messy quality.
