This has not been the reality for way longer than you assume. For instance: in the late 90s, before the 2000s tech boom, Delphi and Visual Basic dominated business programming and most coders had no idea about any of those things. Same for Java and .NET later. On the web side, Perl/CGI was king. After that we had PHP, Java, Ruby, Python, C#. It never really got simpler. If anything, things are more complicated today: mobile development, frontend frameworks, functional programming, Docker and Kubernetes, more complex design patterns. Just a simple "hello world" today with NPM, React, backend MVC, K8s and deployed in AWS is ten times more complicated than anything most of us ever did in the late 90s or early 2000s. It was mostly embedded programmers having to worry about the things you mention, but most of the ones I know from the early 2000s think that our current web stacks are way more complex than what they do.
