Oh certainly. It’s not about university versus no university; I’ve worked with electrical and mechanical engineers who didn’t have degrees, and programmers as well of course. Generally non credentialed engineers make up in ambition and raw intelligence what they lack in schooling. It’s the credentialed engineers who spent four to six years at university and didn’t learn the foundational material that I avoid. The disregard for systematic knowledge they pick up in school stays with them in the workplace, even decades later.
