Why do C++ programmers are not interested in D?

The conclusion is based solely on my own observations as a 
language newbie. But what triggered me is that one of the PyTorch 
core C++ developers didn't even consider D although the language 
clearly fits nicely in the machine learning domain and has been 
proven to be used exactly for that (see Vectorflow, 
https://github.com/Netflix/vectorflow).

Let me just stress my concern that having a deep learning library 
for D these days would give it a huge boost in popularity as it 
once did for Lua, alas.
