That's true, and also unfair, however if believe if we are supportive rather than dismissive or aggressive towards these experiments regardless of who they come from then we can create a culture of encouraging people to try things. Many people may read his article and be inspired to try their own experiments, and even if they're low level they will increase empathy and consideration for blind people. We can't go from ignorant to perfect in a day, I believe we need to create a culture that leads in the direction that we want to go.
