The best language to write a program in is a Turing-complete programming language specially designed for that task, not some cobbled together UI-definition language with ad hoc add-ons to processing.
And yet, most people wear mass-produced clothes.
Each type of wood is used for aging different spirits. Oak is most common in whiskey and wine making. Sometimes the barrels are even smoked near a fire to impart a unique flavor into the alcohol that will be held in the barrel. A used barrel is very desirable and can go for higher prices on the open market than even a quality new barrel. This price parity is due to the unique flavor that can be impacted by using a used wine barrel for whiskey, used whiskey barrel for wine, or some other unique alternation of barrel contents.
Barrels that are hundreds of years old, and thick with aged bacteria are used for making traditional Japanese soy sauce. These special family heirloom barrels will be used for many generations before they are eventually retired. [4]

Like it or not, the whole low code movement is about this.
Let's say your GUI has several input boxes. You want to validate those boxes. You need something Turing-complete to do this, because if it isn't Turing complete and the tool is used by lots of people, someone's GUI will require it.

That's OK provided you accept that it limits what can be done.
