If C++ died for services under Unix and medium sized indie games (such as I2PD, or Cataclysm DDA and its forks) and these where rewritten in Go the maintenance would be far greater in these projects. A GC, a much better cross compatibility and your code for sure could probably be compiled in 10 years.

Also CDDA:Bn wouldn't damn need a > 40h long build using 1.5 GB of RAM under an n270 netbook. Ditto with Nchat, FFS, which is worse. A Golang counterpart for nchat as a TG client (and tdlib rewritten in Go) would weight far less while compiling and maybe even the binary itself, and performance wise it would be similar.

I still remember tons of C++ projects from 2005-2009 impossible to compile today but with GCC 4.3 or GCC 4.9, can't remember. Not because of the size, but because C++ incompatible changes over the years. At least tons of C code will compile it today as is modulo some POSIX changes from C code pre 1996. C++ it's something that should died long ago, among stuff like locales under Unix. UTF8 everywhere, use your own currency and the like.

Yeah, I know, game engines, and tons of physics engines and libraries even FLOSS ones such as OGRE, gdal and the like are C++ domain. Still, most of these could be ported to C.
