"Webdev" makes me think of wordpress, which is like planting 20 onions in your backyard, and comparing yourself to a farmer with acres of crops.

I can completely believe someone had no idea what they were doing when copy/pasting, and working on wordpress.

Yeah, and the business people could not care less. I am on a team taking in millions of dollars from a Delphi Windows app from 1997. Zero tests, horribly mangled business logic embedded in UI handlers. Maintaining that app is not feasible. I'm rebuilding a modern version of it only because it is embarrassing to demo and is such a UX nightmare that our distributor made us commit to a new app.
