>The relevance is that a compiler running in 90's hardware is able to beat Go's compilation speeds of 2017

And beat 99% of other compilers today, meaning that overall compiler complexity has grown.

>If you want the 2017 version of it, it is called Delphi.

Ok, this is something actually relevant.

>Go's compilation speed only surprises those developers that never used anything else beyond C and C++.

For me (tm), Go compilation speed has compared equal or favorably against C, C++, Java, C#, Rust at least.
