Even embraer says that this is just a concept at this point, and faces pretty serious challenges - not just from a technical perspective, but from a regulatory and public perception stance too. And at best, the prototyep is 10-15 years away.

So I wouldn't lose too much sleep over it just yet. I will probably happen some day, but I don't think I my lifetime.
