"simpler and faster" is not enough, as the key to beat TS is interop with existing ecosystem.

You can have a "simpler" type system yet still end up with an overall less convenient DX. As for "faster", really who cares. I feel that these people in big tech who comes up with these stuff, with their massive codebases, have different pain points to most of us.

The fact that they spent the last how many years changing syntax around doesn't give a good impression on priority either. To be fair, this whole thing started as an OCAML syntax, which is a questionable motivation in the first place.
