Writing this caused me to look at  to see if I was completely off. I do see some similarities but also a big difference, at this point of time, in terms of Pony's greater professionalism and claim's to rigour.
But if you consider that "it might or might not exist, it could be vapor, or merely under wraps, we don't know yet" -- which is reasonable, then the comparison to Pony is clear:
Pony (a language with tons of similar great features and no big corporate funding behind it) does exist, and THUS it's not impossible for another language like that to be made.
In this day an age, we constantly see quite good languages coming from apparently nowhere. I'd add Nim, Zig, Crystal, and others to the list.
So, parent's point is: V might not exist at all, but that's not because it's too farfetched to exist.
