configuring vanilla emacs from scratch is certainly a lot of work. There's various distributions (Doom emacs, Spacemacs) that while not perfect have a pretty decent 'new user' experience without too much work. I don't use Go too much but I've done some projects in it. I just uncommented (go +lsp) in Doom's init.el, ran doom sync, restart emacs, and everything just worked, I didn't feel that need to configure anything further.
