No it won't, unless we build infrastructure for them to work with.

Even worse, given modern security standards, I wouldn't be surprised if programming and scripting were to be prohibited in the next ten years or so.

It seems like a negative feedback loop or something, nobody uses these sorts of features, so nobody implements them, and then the skills are less useful…

Microsoft Excel (or cloud-based spreadsheets) will always be allowed. Even if they remove scripting abilities, a clever person can remove a lot of office busy work with just basic Excel functionalities like pivot tables.

Basic scripting abilities would be beneficial years later for the subset of the kids who become office drones.

I would agree with your assessment about 'immediately beneficial in daily life', if you were talking about a course offered to adults who are already working a white collar job.
