There is no question that in the future coding is going to get easier and easier. But something I feel you are missing is that we as an industry are working hard to not just make it easier but make it go away entirely.
Even if we ignore stuff like the buzz about automating away code writing entirely to AI (which I don't see happening but feel the need to mention) modern programing frameworks already rely heavily on system generated code. When is the last time you actually had to write your own sorting algorithm or implement a wholly custom data structure? Hell, if you've ever come into contact with modern web Java you will have seen things like EJB which let you literally generate a database, a web site and all the required interconnections just by writing up a small number of classes. And of course, there is the whole direct design to code generation that's been going on with UML since it's inception.
So whilst in the near term we will indeed see these systems developing to such a state that you could conceive an office with a single university graduate engineer lording over a bunch of high school grade coders in the not even so long term all that will be left is that engineer.
