AFAIK, if you're targeting mainland China and don't need to read anything historic, simplified should be enough. Anywhere else, you would need to learn them. I quite like this YouTuber for various linguistic stuff on Chinese: https://www.youtube.com/watch?v=V8EFhnMaVRk

Oh yeah, definitely, although I'm more concerned about committing them to memory, since the simplified characters lose some meaning and you're expected to make up for it. I guess I've forgotten the meaning of simple kanji like 免 one too many times. Thanks for the link, though! I'll check it out.
