 Not happy 

I am not happy with the tone of this comment, ""You seem to be confused"".  
Firstly, are you seriously saying that as ""Product Manager, VisualEditor team"" you are completely unable to give a useful answer to a question about what the plans for mathematics rendering are or what progress has been made against those plans?  Does mathematics rendering really have nothing whatsoever to do with Visual Editor?  Or is there some other reason why you prefer not to answer the question?
Secondly, if you wanted to be helpful, instead of airily alluding to ""the volunteers who maintain that extension"" you might have said who they are.  Who are the people to whom, in your opinion, I should address that question, please?
Thirdly, if you really wanted to be helpful, and I am finding it hard to avoid the conclusion that you do not, you might even have volunteered to pass the question on to the approriate people rather than batting it back so unhelpfully.
Once again, if you engage constructively with the volunteer mathematics editor community, it is likely to prove of benefit to the project.  So far I'm seeing less of a serious attempt to engage and too much petty point-scoring.    "
