I would be interested in hearing more about your point. TCL is an elegant scripting language, very LISP-y, where most data structures are lists of strings. Go on the other hand is more like a modern mix of C and Pascal with GC and lots of convenient libraries, and which builds statically. The performance of TCL and Go are also a world apart.
Go is a worse Java 1.1. The only remotely interesting part is virtual threads.
Might as well use Java 19 then. Why not, really. Because Java is boring?
