I don't want to do front-end anymore
It's disheartening to explain this over and over again, but these frameworks are a-ok because user's expectations for the web have grown astronomically. The complicated web is here because users insist on interaction, and if any web page has more than around 10 interactions on it, the resultant complexity is best handled by a framework. I recently got to do a jQuery job for a client-- it wasn't a pleasant blast from the past but a kludgey swamp to slog through.The build pipeline complaint also strikes me as hollow. Create React App outputs folder you can drag and drop onto a  server and serve, same for Angular and I would assume Vue. Yes, it is a lot of JS from a ton of NPM libraries, but that's the trade-off when you get an entire ecosystem of code for free. If your application is security critical then consider either writing your own libraries or hosting security vetted copies of the libraries.The real reason to leave this industry is that it's all the same work at the end of the day. Despite what application you build, whether it's a social network, a security application or collaborative tool like Figma or Trello, it all runs together as a mish-mash of views, data and DOM elements. Unless you're really invested in the product, it becomes hard to maintain enthusiasm. You can only roll a CSS library, or auth scheme or API library so many times before you're ready to start some new adventures in coding.
