Leveraging the great node ecosystem comes at a significant cost in terms of power consumption, complexity of the manufacturing process, board size and of the system itself.
Power consumption and, to some extent, board size have been very significant drags for the Internet of Everything. Mindlessly throwing libraries at them just to help people who are too lazy to learn a new programming technology is only adding a drag on it.
I certainly don't want to drag this into the mud. It's certainly a good learning platform which can provide exposure to a range of devices for people who would otherwise not even hear about them, or for whom the initial technological barriers would be too high to overcome in a single evening. But this is far, far from adding any kind of value to the struggle towards universal Internet connection.
