Ask HN: Do you feel the quality of SWE has gone down?

It feels like a lot engineers now days don't seem to have a good cs background. They don't seem to understand things like cache, paging, virtual memory,cpu pipelines, algorithms or other things pretty important to CS.

I know we have a lot of bootcamps and people are joining because it pays decently, but is this necessarily a good thing for the industry?

When we have the next industry crash (.com crash) will these people stick around?
