it's faster, builds a proper parse tree so is more reliable, it's shared between editors so will have greater opportunity for improvement, and exposes related things like indentation and code movement from the same system.
it's very very cool that this late in the world of computers we ~suddenly get cross-editor analysis system (LSP) and cross-editor highlighting/indentation/rough parsing support.
Cross-editor? Who runs multiple editors? The only thing you need is Emacs. Why are they breaking apart Emacs' functionality into separate things? Is TreeSitter even written in Lisp? If not, then how would this be hackable in the same way?
