IMO this is unfair characterization.
If using Photoshop is driving, programming is building an internal combustion engine vehicle. You cannot expect to just randomly google for car-making tutorials and get an SUV done in a weekend. Heck, you can't even expect to be able to build a very simple combustion engine from basic principles without a lot of study.
I'm not saying this is Aella's fault or anything, it's fair to have wrong expectations, but calling this "needlessly complicated" is not fair either.
If I had to take something away from that Twitter thread is how marvelous is that someone without any programming experience has been able to programatically manipulate CSV data in a couple of days.
