Hey Keshav!
I think it's a more complicated story than that. Our ambition is larger than converting existing functional language programmers -- a lot of whom are happy (and passionate) about their current tools.
I think it is a much wider stratum of smart people who want to do things that were hitherto impossible (or impractical) without a vast amount of built-in knowledge and algorithms. And their potential will be unlocked by the "curated computing experience" that we provide.
Personally, I want everyone to be able to do the kinds of cool things that I regularly do on weekend projects, and that I know cannot be achieved in anything other than Wolfram Language.
And frankly, it'll be good for all of us to have an influx of new people with new ideas from different backgrounds who want to build and compute new and different kinds of things. Our tribe is still quite homogenous.
Although I suspect that at first it will be threatening to those of us who derive our pride (and job security) from being masters of somewhat arcane tools, processes, and knowledge.
