Yes. At least since late '90s, and certainly the last 2 decades.

I blame the rise of frameworks, libraries, and IDEs. It's easier for someone who knows nothing to throw some software together and ship it. In the good old days, all software had to be written by someone who knew what they were doing, often in difficult tools. You had to think ahead and write code correctly, because you couldn't just ship patches every week.

And as junior devs get replaced by AI, there won't be any experience for any of them to learn how to do that.
