Is it really needed (Score 1)

Okay conceptually it's brilliant, and possibly even the direction in which computing as a whole is going, while us retro geeks resist and resist. But I have to wonder is it really necessary to invent a whole new language. We already have many languages that are both efficient and effective. Would the time not be better spent building front ends to existing languages (uggh the retro geek in me cringes at the thought).
