I posit that the reasons are
- the need for conservatism and slowing down progress is inherent in people. Last time it was opposing LGBTQ and racial discrimination and now it is technology. Its the same mode of opposition, people just don't like chaotic progress.
- people who have good jobs and high status want to _conserve_ it and not lose position - tech industry keeps threatening the status quo again and again
- for some reason cynicism is seen as signalling a more mature worldview while optimism is seen as childish when the historical trend points to optimism instead
