Arguably better async primitives too. Python's main advantage at this point feels like a stronger ecosystem of packages calling into native code (eg numpy et al mostly call optimized C routines). If Typescript adds more of those libraries (like this one), then I could see it gaining a lot of adoption.
I think Bun (which has typescript embedded but written in zig) would be a great place to experiment.
I could see it adding some tensor types that drop into zig code that uses webgpu bindings. And add some operator overloading so you could just add t1 + t2 etc.
