rust is just massively promoted
go is a project that google funded in order to get better bang per buck for their internal dev shop that was previously using C++, and Rob Pike (plan nine and newsqueak and unix doc writer) and Ken Thompson (inventor of B, the predecessor of C) and Richard Griesemer (who built the chrome javascript engine to reduce their training costs and maintenance costs and shorten the edit/test cycle
they never bothered to advertise it very much
you can look up the history of rust, it is not as notable or effective, just a gigaton of bullshit shilling everywhere
