Do you agree that Gates’ scheme to reinvent the toilet is ‘too high-tech’

Hell everyone I read this article on Gates' scheme to reinvent the toilet is ‘too high-tech' . It says that

1. The Gates Foundation's challenge aims to deliver energy-producing toilets

2. An NGO worker and an engineer say low-cost, robust toilets are needed instead

3. But it is hard to predict world-changing innovation, says a Gates director

What do you think about this issue?
