Sure, if you make vague enough statements, they're hard to disprove, which might lead you to believe that what you said is correct even though you haven't made a provable or disprovable claim.

There are plenty of problems where one might consider using Go or Rust. The same cannot be said of Go and Racket, or Rust and Racket. I wouldn't consider using Racket for a situation where I need high performance or low memory usage--the numbers just don't work. Likewise I wouldn't look at Go or Rust for building a data-presentation type webapp.
