Most microservices I've seen implemented are not actually microservices. Most teams (unless they are developing "simple" web or mobile applications) have no idea who is consuming their services, or how, or if what they've made is working correctly. They frequently don't have an understanding of the different models of releasing software, much less of a complete system architecture, failure modes, consistency models, reliability estimates, performance limits, etc. Mostly what I see time and again is a team of people who just write some code that seems to work for them, and then go home, without ever considering how or if it's working in the real world.
I don't know anything about modern computer science education. But it appears that new developers have absolutely no idea how anything but algorithms work. It's like we taught them how hammers and saws and wrenches work, and then told them to go build a skyscraper. There are only two ways I know of for anyone today to correctly build a modern large-scale computer system: 1) Read every single book and blog post, watch every conference talk, and listen to every podcast that exists about building modern large-scale computing systems, and 2) Spend 5+ years making every mistake in the book as you try to build them yourself.
It feels like the industry mostly just re-learns the same mistakes over and over like we're in Groundhog's Day (we're the extras, not Bill Murray). But it's equally possible that I just lack perspective and am expecting too much. Maybe the auto industry at the turn of the 20th century also spent decades re-learning the same lessons over and over, as the novelty of mass-producing complex systems continued to elude us. Hell, the new auto companies still don't get it right.
