"Technology can't solve social problems", first of all: bullshit. Iodized salt and fluoridated water, they count and they are miracles. Vaccines count and they are miracles. Modern logistics are a miracle, tap water is a miracle and all of these things are technologies.
Technology can't solve problems _when powerful people don't want them solved_. But technology in the hands of the people can absolutely solve social problems, the questions are only about who's in the way.
