Earlier quoted context omitted.
Whoever says web is "easy" never had to build or maintain a large web application. The ecosystem is incredibly deep and constantly evolving, to the point where best practices change every six months.
Not to mention; web developers are constantly having to context switch between HTML, CSS, and JavaScript. Old school days they also had a backend language like PHP or Perl. Many still do. Then there was/is SQL. By my count, that's at least five different languages to know all at once.
