I agree with you that reform movements like what is currently building in education can have disastrous effects. However, in this instance, most of the reforms being proposed are a product of observing what has worked in charter schools, rather than a product of running in the opposite direction of what doesn't work.
I see the current reform movement as an overwhelmingly positive force in education. As long as they stick to the ideal of spreading successful charter school practices to the broader public school community I'll be happy.
PS: All you genius hackers with backgrounds in machine learning, AI, social networking, (god knows what else might be applicable). Don't like the way teacher performance is being quantified? There's a multi-billion dollar industry that could use some disruption.
