Web development is definitely a viable industry. Unfortunately there's not a single stack that you "should" learn above all the rest - the best choice would likely depend on your career goals. If you want to work for a team in your region, find out what stacks are popular there - going to local meetups might be a great way to figure out what to expect. If you want to freelance, you might choose to begin with a kitchen sink-like framework like Wordpress or Drupal. A lot of software development bootcamps like to start with Ruby on Rails, which makes good sense as well. tl;dr it depends.
