No i mean that a single person or small group can’t make a general-purpose language that would beat TS, Rust, Java, Swift, Go, etc.

All these languages are supported by huge groups. They have hyper-optimized compilers or JIT, IDE integration, libraries, and adoption.

If you can form a huge group, then you can beat these languages. Or if you target a niche. Or if you can use existing tooling (transpiling, LSP, effective existing libraries), and spend a lot of time and effort. Imba seems to be taking the third approach.
