Agree that I may be hyperbolical at times and this can be detrimental to fruitful discussion. I'll be more mindful of it, thanks! More accurate is that the REPL/notebook style is currently so much more convenient to get started and to "explore" with that people will use that and it's what all Julia examples etc teach. Pluto.jl may be a good "transition" from this though, although I'm afraid modularization is still too inconvenient with it. The script-workflow latency is also a reason why "scripters" don't switch to Julia even though they otherwise would. So while the it's not practically impossible as I hyperboled, it is IMHO a blocker for wider Julia adoption and a transition to better programming practices. In my experience in both teaching and helping working scientists with their code problems I think the current situation that REPL/notebook is so much easier to get started with is at least a major reason why better practices don't get adopted. Scientists themselves doing any programming is quite a recent thing. Usually it was "lab engineers" doing "the coding" and data mangling and the scientist doing "the analysis" in something like SPSS or Excel or copypasted R oneliners. It's also really understandable why scientists don't make much effort to learn and enforce good programming. It's a relatively minor part of their job, they manage to scrape much of the analysis together with poor practices, and when it almost inevitably explodes as the analysis gets more complicated, someone "more technical" gets called to fix the mess (I do this all the time). In most languages modularizing code is made needlessly hard, and I'm smelling something like this in Julia module system (and in e.g. Python packaging). I sometimes wonder if there's some (unconscious) gatekeeping to keep "the using" and "the programming" (and "the core development") apart artificially. You actually sometimes encounter explicit statements like this (Linus Torvalds famously about C++ but in this post's discussion something like that not knowing R means that you shouldn't use ML (which is extra bizarre because very very few actually know R)). The benefits of modularization are also not easy to foresee until you learn from many hard lessons of ending up with unmanageable sphagetti or analysis that is wrong but it may be even impossible to pin out why due to lack of reproducible code. And if you don't know about the ways of avoiding/mitigating this, you're not really equipped with learning the lesson. When this compounds with significant hurdles to do "the right thing" I find it almost inevitable that "the right thing" will not get adopted. As a sidenote I find it also quite odd why so little effort is done to "show the work" with data analysis when it's literally required when you do it in math class. I think they are almost the same thing. Maybe it stems from the computer seen as a calculator and "the work" is done on paper, but this is mostly due cultural lag from the era where computers were in practice calculators.
