As someone who is in the position to see what the next really disruptive innovation is, you're quite right that there exist much, much better ways to write and collaborate on code. Flying leaps of innovation to Zed's tiny shuffle-steps.
Zed spent their innovation budget on Rust and GPUI, and as a result they have no energy to question the status quo of IDEs as a whole. Git and LSP are antiquated but form the bedrock of their plans for the future.
Essentially at this point they can only do spaghetti enigneering: adding more and more complexity on top of the complexity that already exists. IDEs have been through so many iterations of this process already that all the real wins are in refactoring: moving the whole system (and ecosystem) design sideways, which is he one thing they dare not try to do (though it happens to be my forte).
BABLR -- a parser framework, and agAST, the DOM structure at the heart of our state layer. Come to our Discord if you want to learn more. We're trying to launch in the next day or two here.
