I've been working >10 years as a software engineer. If I'd never worked on a (necessarily) complicated system(s), I could maybe understand your viewpoint. Churning out the same CRUD app with minor differences would probably be safe enough to expect a junior dev to 'have at it'.

Unfortunately, this is the current 'thinking' on how some un-enlightened people think the industry should work. Ultimately, I think this is a load of nonsense. Software engineering is engineering. Some people may have snuck in & survived as they never had to do something non trivial & deal with the resulting consequences.
