The problem is that the only source of information for those who are not involved in these fields is basically hollywood and other futuristic dystopian movies where "technology is the great evil".
Just because vaccines exist now, birth-rate has increased. In the past, families had to bear about 5, 6 or 7 children because only half or less of them would reach adulthood. That problem has been eradicated, thanks to the advance of technology. Now, we are able to make brain cells from the skin, making regeneration a solid prospect for the future. Maybe a lot of problems that are common now will also be eradicated, yet people only seem to believe on the idea that the government will be authoritarian and use technology against their people. And that's politics, my friend. Communism is just socialism with electricity, just because Stalin had access to AC electricity it doesn't mean that the rest of the world was also under an authoritarian government and used that technology to abuse their people.
