This reads to me like very blinkered & elitist thinking. Repetition makes things easy, we are good at what we practice doing. A normal computer user rarely needs to do something that might be more efficient in markdown, command line, whatever, so their speed in doing that will be slower compared to a graphical interface. Normal computer users want programs with dropdown menus and they are faster with those than we are when we have to look up a command or function that we rarely use. I know people who can filter & pivot a complex dataset quicker in Excel than I can in SQL. I think it is safe to say that most programmers occasionally encounter something they need to Google for and dig through some stack overflow posts to find the syntax. That would be necessary almost constantly for a non-programmer and it's just not an efficient use of time.
