The problem with C/C++ and "newer" languages is that programs need to be individually compiled or have an interpreter installed to execute them - the main problem the author is solving.

The author precisely realises that there used to be multiple architectures, just like you, but also notices that we have converges on x86-64 - what she terms the lingua franca.

I also completely follows her sentiment, that we should not switch ISA unless there is a very real computation per power unit benefit of doing so.
