Imo that thinking is wrong because it makes this assumption that doing anything at all with a gui is easy and frictionless. I don't know how to do anything in excel. If I have to look up how to make a plot in excel, I will have to find some article on the internet of how to do that in my particular excel version. Excel is tough software to use that only becomes easier after you spend time with it (hint hint, just like programming). If I don't know how to make a plot in R, I might also have to find an article. It's no different, no harder, usually easier in fact, to just do the job in R. All these common tasks in R or excel are all 5 min articles worth of information you have to cram in your head.
It's not hard to code, children do it. I'd love to see spreadsheet power users realize that they could be working with much simpler things like parsing plain text files with a few lines of code rather than trying to open some macro heavy spreadsheet on the shared network drive that takes 5 mins just to open on the work issued workstation. I'd guess it would be up to business programs and accounting programs and all these other college majors to actually teach classes in python and R, rather than what they do now which is teach classes in excel. Imo the entrenchment in excel is rooted in ignorance to other (often simpler) options available with python or R, than in any actual critical proprietary features offered by excel. Microsoft is probably pretty happy that their software is so baked into these different academic curriculums, keeping it alive in industry going forward for an entire working persons career after college.
