Software engineering is only about 20% writing code (the famous 40-20-40 split). Most people use it only for the first 40%, and very succesfully (im in that camp). If you use it to write your code you can theorettically maybe get 20% time improvement initially, but you loose a lot of time later redoing it or unraveling. Not worth bothering.

20% is one of those cool lies SWEs have been able to push through (like “our jobs are oh so very special we can’t really estimate it, we’ll create an entire sub-industries with our industry to make sure everyone knows we can’t estimate”).

SWEs spend 20% of the time writing code for exactly the same reason brick-layers spend 20% of their time laying bricks
